In Koine Greek, the letter Mu was a bilabial nasal, made by closing the lips and allowing the voice to resonate in the nasal cavity. It was pronounced similar to the “m” in “mother.”

Numerical significance

Mu corresponds to the number forty (40) in the Greek numerical system (isopsephy). In Judeo-Christian contexts, forty often symbolizes a period of trial or testing. It can also be seen as a significant milestone number, representing a substantial quantity or duration.
