Also noteworthy is its consistent use of the Tetragrammaton, יהוה, God’s holy name, Jehovah, in Hebrew.

Other Valuable Manuscripts

The divine name also appears in another manuscript from this same cave, now known as Cave 1. In a commentary on the book of Habakkuk, the Tetragrammaton appears four times in paleo-Hebrew letters, an older style that contrasts with the more familiar square Hebrew lettering.​—See the footnote to Habakkuk 1:9, Reference Bible.

The Leviticus manuscript uses IAO, for the Hebrew יהוה, the divine name of God, instead of the Greek Kyʹri·os, “Lord.”a

It dates from the first half of the first century C.E. and contains parts of 41 psalms. The Tetragrammaton is written some 105 times in ancient paleo-Hebrew characters, making it stand out amid the square Hebrew script of the context.
