1 Chronicles 23 (WEBP)
 Now David was old and full of days; and he made Solomon his son king over Israel.
 He gathered together all the princes of Israel, with the priests and the Levites.
 The Levites were counted from thirty years old and upward; and their number by their polls, man by man, was thirty-eight thousand.
 David said, “Of these, twenty-four thousand were to oversee the work of Yahweh’s house, six thousand were officers and judges,
 four thousand were doorkeepers, and four thousand praised Yahweh with the instruments which I made for giving praise.”
 David divided them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.
 Of the Gershonites: Ladan and Shimei.
 The sons of Ladan: Jehiel the chief, Zetham, and Joel, three.
 The sons of Shimei: Shelomoth, Haziel, and Haran, three. These were the heads of the fathers’ households of Ladan.
 The sons of Shimei: Jahath, Zina, Jeush, and Beriah. These four were the sons of Shimei.
 Jahath was the chief, and Zizah the second; but Jeush and Beriah didn’t have many sons; therefore they became a fathers’ house in one reckoning.
 The sons of Kohath: Amram, Izhar, Hebron, and Uzziel, four.
 The sons of Amram: Aaron and Moses; and Aaron was separated that he should sanctify the most holy things, he and his sons forever, to burn incense before Yahweh, to minister to him, and to bless in his name forever.
 But as for Moses the man of God, his sons were named among the tribe of Levi.
 The sons of Moses: Gershom and Eliezer.
 The sons of Gershom: Shebuel the chief.
 The son of Eliezer was Rehabiah the chief; and Eliezer had no other sons, but the sons of Rehabiah were very many.
 The son of Izhar: Shelomith the chief.
 The sons of Hebron: Jeriah the chief, Amariah the second, Jahaziel the third, and Jekameam the fourth.
 The sons of Uzziel: Micah the chief, and Isshiah the second.
 The sons of Merari: Mahli and Mushi. The sons of Mahli: Eleazar and Kish.
 Eleazar died, and had no sons, but daughters only; and their relatives, the sons of Kish, took them as wives.
 The sons of Mushi: Mahli, Eder, and Jeremoth, three.
 These were the sons of Levi after their fathers’ houses, even the heads of the fathers’ houses of those who were counted individually, in the number of names by their polls, who did the work for the service of Yahweh’s house, from twenty years old and upward.
 For David said, “Yahweh, the God of Israel, has given rest to his people; and he dwells in Jerusalem forever.
 Also the Levites will no longer need to carry the tabernacle and all its vessels for its service.”
 For by the last words of David the sons of Levi were counted, from twenty years old and upward.
 For their duty was to wait on the sons of Aaron for the service of Yahweh’s house—in the courts, in the rooms, and in the purifying of all holy things, even the work of the service of God’s house;
 for the show bread also, and for the fine flour for a meal offering, whether of unleavened wafers, or of that which is baked in the pan, or of that which is soaked, and for all measurements of quantity and size;
 and to stand every morning to thank and praise Yahweh, and likewise in the evening;
 and to offer all burnt offerings to Yahweh on the Sabbaths, on the new moons, and on the set feasts, in number according to the ordinance concerning them, continually before Yahweh;
 and that they should keep the duty of the Tent of Meeting, the duty of the holy place, and the duty of the sons of Aaron their brothers for the service of Yahweh’s house.

1 Chronicles 23 (KJVS)
 So when David H1732 was old H2204 (8804) and full H7646 (8804) of days H3117, he made Solomon H8010 his son H1121 king H4427 (8686) over Israel H3478.
 And he gathered together H622 (8799) all the princes H8269 of Israel H3478, with the priests H3548 and the Levites H3881.
 Now the Levites H3881 were numbered H5608 (8735) from the age H1121 of thirty H7970 years H8141 and upward H4605: and their number H4557 by their polls H1538, man by man H1397, was thirty H7970 and eight H8083 thousand H505.
 Of which H428, twenty H6242 and four H702 thousand H505 [were] to set forward H5329 (8763) the work H4399 of the house H1004 of the LORD H3068; and six H8337 thousand H505 [were] officers H7860 (8802) and judges H8199 (8802):
 Moreover four H702 thousand H505 [were] porters H7778; and four H702 thousand H505 praised H1984 (8764) the LORD H3068 with the instruments H3627 which I made H6213 (8804), [said David], to praise H1984 (8763) [therewith].
 And David H1732 divided H2505 (8735) them into courses H4256 among the sons H1121 of Levi H3878, [namely], Gershon H1648, Kohath H6955, and Merari H4847.
 Of the Gershonites H1649 [were], Laadan H3936, and Shimei H8096.
 The sons H1121 of Laadan H3936; the chief H7218 [was] Jehiel H3171, and Zetham H2241, and Joel H3100, three H7969.
 The sons H1121 of Shimei H8096; Shelomith H8019 (8675) H8013, and Haziel H2381, and Haran H2039, three H7969. These [were] the chief H7218 of the fathers H1 of Laadan H3936.
 And the sons H1121 of Shimei H8096 [were], Jahath H3189, Zina H2126, and Jeush H3266, and Beriah H1283. These four H702 [were] the sons H1121 of Shimei H8096.
 And Jahath H3189 was the chief H7218, and Zizah H2125 the second H8145: but Jeush H3266 and Beriah H1283 had not many H7235 (8689) sons H1121; therefore they were in one H259 reckoning H6486, according to [their] father’s H1 house H1004.
 The sons H1121 of Kohath H6955; Amram H6019, Izhar H3324, Hebron H2275, and Uzziel H5816, four H702.
 The sons H1121 of Amram H6019; Aaron H175 and Moses H4872: and Aaron H175 was separated H914 (8735), that he should sanctify H6942 (8687) the most H6944 holy things H6944, he and his sons H1121 for H5704 ever H5769, to burn incense H6999 (8687) before H6440 the LORD H3068, to minister H8334 (8763) unto him, and to bless H1288 (8763) in his name H8034 for H5704 ever H5769.
 Now [concerning] Moses H4872 the man H376 of God H430, his sons H1121 were named H7121 (8735) of the tribe H7626 of Levi H3878.
 The sons H1121 of Moses H4872 [were], Gershom H1647, and Eliezer H461.
 Of the sons H1121 of Gershom H1647, Shebuel H7619 [was] the chief H7218.
 And the sons H1121 of Eliezer H461 [were], Rehabiah H7345 the chief H7218. And Eliezer H461 had none other H312 sons H1121; but the sons H1121 of Rehabiah H7345 were very H4605 many H7235 (8804).
 Of the sons H1121 of Izhar H3324; Shelomith H8019 the chief H7218.
 Of the sons H1121 of Hebron H2275; Jeriah H3404 the first H7218, Amariah H568 the second H8145, Jahaziel H3166 the third H7992, and Jekameam H3360 the fourth H7243.
 Of the sons H1121 of Uzziel H5816; Michah H4318 the first H7218, and Jesiah H3449 the second H8145.
 The sons H1121 of Merari H4847; Mahli H4249, and Mushi H4187. The sons H1121 of Mahli H4249; Eleazar H499, and Kish H7027.
 And Eleazar H499 died H4191 (8799), and had no sons H1121, but daughters H1323: and their brethren H251 the sons H1121 of Kish H7027 took H5375 (8799) them.
 The sons H1121 of Mushi H4187; Mahli H4249, and Eder H5740, and Jeremoth H3406, three H7969.
 These [were] the sons H1121 of Levi H3878 after the house H1004 of their fathers H1; [even] the chief H7218 of the fathers H1, as they were counted H6485 (8803) by number H4557 of names H8034 by their polls H1538, that did H6213 (8802) the work H4399 for the service H5656 of the house H1004 of the LORD H3068, from the age H1121 of twenty H6242 years H8141 and upward H4605.
 For David H1732 said H559 (8804), The LORD H3068 God H430 of Israel H3478 hath given rest H5117 (8689) unto his people H5971, that they may dwell H7931 (8799) in Jerusalem H3389 for ever H5769:
 And also unto the Levites H3881; they shall no [more] carry H5375 (8800) the tabernacle H4908, nor any vessels H3627 of it for the service H5656 thereof.
 For by the last H314 words H1697 of David H1732 the Levites H3881 [were] numbered H4557 from twenty H6242 years H8141 old H1121 and above H4605:
 Because their office H4612 [was] to wait H3027 on the sons H1121 of Aaron H175 for the service H5656 of the house H1004 of the LORD H3068, in the courts H2691, and in the chambers H3957, and in the purifying H2893 of all holy things H6944, and the work H4639 of the service H5656 of the house H1004 of God H430;
 Both for the shewbread H3899 H4635, and for the fine flour H5560 for meat offering H4503, and for the unleavened H4682 cakes H7550, and for [that which is baked in] the pan H4227, and for that which is fried H7246 (8716), and for all manner of measure H4884 and size H4060;
 And to stand H5975 (8800) every morning H1242 to thank H3034 (8687) and praise H1984 (8763) the LORD H3068, and likewise at even H6153;
 And to offer H5927 (8687) all burnt sacrifices H5930 unto the LORD H3068 in the sabbaths H7676, in the new moons H2320, and on the set feasts H4150, by number H4557, according to the order H4941 commanded unto them, continually H8548 before H6440 the LORD H3068:
 And that they should keep H8104 (8804) the charge H4931 of the tabernacle H168 of the congregation H4150, and the charge H4931 of the holy H6944 [place], and the charge H4931 of the sons H1121 of Aaron H175 their brethren H251, in the service H5656 of the house H1004 of the LORD H3068.
Young’s Literal Translation
1 Chronicles 23 (YLT)
 And David is old, and satisfied with days, and causeth his son Solomon to reign over Israel,
 and gathereth all the heads of Israel, and the priests, and the Levites;
 and the Levites are numbered from a son of thirty years and upward, and their number, by their polls, is of mighty men thirty and eight thousand.
 Of these to preside over the work of the house of Jehovah are twenty and four thousand, and officers and judges six thousand,
 and four thousand gatekeepers, and four thousand giving praise to Jehovah, ‘with instruments that I made for praising,’ saith David.
 And David distributeth them into courses: Of the sons of Levi: of Gershon, Kohath, and Merari.
 Of the Gershonite: Laadan and Shimei.
 Sons of Laadan: the head is Jehiel, and Zetham, and Joel, three.
 Sons of Shimei are Shelomith, and Haziel, and Haran, three; these are heads of the fathers of Laadan.
 And sons of Shimei are Jahath, Zina, and Jeush, and Beriah; these are sons of Shimei, four.
 And Jahath is the head, and Zizah the second, and Jeush and Beriah have not multiplied sons, and they become the house of a father by one numbering.
 Sons of Kohath are Amram, Izhar, Hebron, and Uzziel, four.
 Sons of Amram: Aaron and Moses; and Aaron is separated for his sanctifying the holy of holies, he and his sons-unto the age, to make perfume before Jehovah, to serve Him, and to bless in His name-unto the age.
 As to Moses, the man of God, his sons are called after the tribe of Levi.
 Sons of Moses: Gershom and Eliezer.
 Sons of Gershom: Shebuel the head.
 And sons of Eliezer are Rehabiah the head, and Eliezer had no other sons, and the sons of Rehabiah have multiplied exceedingly.
 Sons of Izhar: Shelomith the head.
 Sons of Hebron: Jeriah the head, Amariah the second, Jahaziel the third, and Jekameam the fourth.
 Sons of Uzziel: Micah the head, and Ishshiah, the second.
 Sons of Merari: Mahli and Mushi; sons of Mahli: Eleazar and Kish.
 And Eleazar dieth, and he had no sons, but daughters, and sons of Kish their brethren take them.
 Sons of Mushi: Mahli, and Eder, and Jerimoth, three.
 These are sons of Levi, by the house of their fathers, heads of the fathers, by their appointments, in the number of names, by their polls, doing the work for the service of the house of Jehovah, from a son of twenty years and upward,
 for David said, ‘Jehovah, God of Israel, hath given rest to His people, and He doth tabernacle in Jerusalem unto the age;’
 and also of the Levites, ‘None are to bear the tabernacle and all its vessels for its service;’
 for by the last words of David they took the number of the sons of Levi from a son of twenty years and upward,
 for their station is at the side of the sons of Aaron, for the service of the house of Jehovah, over the courts, and over the chambers, and over the cleansing of every holy thing, and the work of the service of the house of God,
 and for the bread of the arrangement, and for fine flour for present, and for the thin unleavened cakes, and for the work of the pan, and for that which is fried, and for all liquid measure and solid measure;
 and to stand, morning by morning, to give thanks, and to give praise to Jehovah, and so at evening;
 and for all the burnt-offerings-burnt-offerings to Jehovah for sabbaths, for new moons, and for appointed seasons, by number, according to the ordinance upon them continually, before Jehovah.
 And they have kept the charge of the tent of meeting, and the charge of the sanctuary, and the charge of the sons of Aaron, their brethren, for the service of the house of Jehovah.
