🔼The name Bichri in the Bible
Sheba leads an insurrection against king David. But David's army commander Joab pursues him as far as the city of Abel, and lays siege to the city until the townsfolk behead Sheba and lob his head over the town's wall. And that's the end of Sheba.
🔼Etymology of the name Bichri
The name Bichri comes from the root-verb בכר (bakar), meaning to rise early:
The final letter yod can have all kinds of functions. It could indicate a possessive (My First Born), or it could be a remnant of יהוה (Yahweh; First Born Of Yahweh). But most sources seem to prefer seeing the yod in the same function that forms the ethnonym: literally: He Of First-Born-ness.
For a meaning of the name Bichri, NOBSE Study Bible Name List reads First Born. Jones' Dictionary of Old Testament Proper Names proposes Juvenile, First Born. BDB Theological Dictionary reads Youthful.
