🔼The name Avith in the Bible
The name Avith occurs twice in the Bible, first in Genesis 36:35 and then in the exact same verse in 1 Chronicles 1:46, except that in Chronicles this name is spelled as עיות, which would transliterate into something like Ayoth.
🔼Etymology of the name Avith
The name Avith comes from the root-verb עוה ('awa), meaning to distort:
There are two ways to interpret this name. It may be a singular word; an old spelling of the noun עוה ('awa), meaning distortion or ruin (favored by NOBSE Study Bible Name List). And it may also be a regular plural of that same noun (favored by Alfred Jones — Dictionary of Old Testament Proper Names).
And so, for a meaning of the name Avith, NOBSE Study Bible Name List reads Ruin, and Jones' Dictionary of Old Testament Proper Names has Ruins. BDB Theological Dictionary doesn't translate our name but confirms it stems from the root-verb עוה ('awa).
Note that the form עוית occurs once in the proper narrative of the Bible in Daniel 4:27, where the main translations translate it with Iniquities.
