If anyone transgresses even one of the commandments of Iaṓ and does not follow it ..." (4:27).

This investigation leads to the conclusion that the ancient pronunciation of the name of the god of Israel was "Yahô", which amounts to saying that the tetragrammaton was originally a trigrammaton. The w in "Yhwh" was not a consonant, but a mater lectionis indicating the sound "o". The letter h at the end of the tetragrammaton Yhwh should be understood as indicating a lengthening of the preceding o.
