Abihail in Fausset's Bible Dictionary
(("father of splendor".)
1. Wife of Rehoboam, king of Judah, daughter, i.e.
descendant of Eliab, David's oldest brother. But Keil argues
that 2 Chronicles 11:19-20 shows that in 2 Chronicles 11:18
only one wife is named; therefore the sense is "Mahalath the
daughter of Jerimoth son of David and of Abihail" (the
daughter of Eliab, etc.)
2. Numbers 3:35.
3. 1 Chronicles 2:23.
4. 1 Chronicles 5:14.
5. Father of Queen Esther, and uncle of Mordecai
(Esther 2:15).
