("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).

(Heb. Abicha'yil, אֲבַיחִיַל , Father Of [i.e. Endowed With ] might, or perhaps leader of the song), the name of three men and two women.
1. (Sept. ‘Αβιχαϊ v Λ . ) The father of Zuriel, which latter was the chief of the Levitical family of Merari at the exode ( Numbers 3:35). B.C. ante 1657.
2. (Sept. ‘Αβιγαία v. r . ‘Αβιχαία .) The wife of Abishur (of the family of Jerahmeel), and mother of Ahban and Molid ( 1 Chronicles 2:29, where the name in some MSS. is Abiha'Yil, אֲבַיהִיַל , apparently by error). B.C. considerably post 1612.
3. (Sept. ‘Αβιχαία .) The son of Huri, and one of the family chiefs of the tribe of Gad, who settled in Bashan ( 1 Chronicles 5:14), B.C. between 1093 and 782.

She is there called the "daughter" of Eliab, the son of Jesse, which must mean descendant [ (See Father) ], since David, the youngest of his father's sons, was thirty years old when he began to reign, eighty years before her marriage.
5. (Sept. ‘Αμιναδάβ v. r. ‘Αβιχαϊ v Α .) The father of Esther, and uncle of Mordecai ( Esther 2:15; Esther 9:29;' comp. 2:7). B.C. ante 479.
International Standard Bible Encyclopedia 
ab´i - hāl ( אביחיל , 'ăbhı̄ḥayil ; in some manuscripts 'abhihayil , when feminine, but best reading is the former: "father, or cause, of strength"): Five persons in the Old Testament are called by this name: (1) A L evite and the father of Zuriel, who in the Wilderness was head of the house of Merari, Levi's youngest son ( Numbers 3:35 ); (2) The wife of Abishur, a man of the tribe of Judah, in the line of Hazron and Jerahmeel ( 1 Chronicles 2:29 ); (3) One of the heads of the tribe of Gad, who dwelt in Gilead of Bashan ( 1 Chronicles 5:14 ); (4) Either a wife of Rehoboam, king of Judah, or mother of his wife Mahalath, according to the interpretation of the text ( 2 Chronicles 11:18 ); probably the latter view is correct, since there is no conjunction in the text, and since ( 2 Chronicles 11:19 ) contemplates only one wife as already mentioned. This being true, she was the wife of Jerimath, a son of David, and daughter of Eliab, David's eldest brother. It is interesting to note this frequent intermarriage in the Davidic house; (5) Father of Queen Esther, who became wife of Xerxes (Biblical Ahasuerus ) king of Persia, after the removal of the former queen, Vashti, ( Esther 2:15; Esther 9:29 ). He was uncle of Mordecai.

Abiha´il (Father of light or splendor), the wife of Rehoboam, king of Judah. She is called the daughter of Eliab, David's elder brother ( 2 Chronicles 11:18); but was doubtless only his descendant.
Abihail (Father of might, i.e. mighty). This name should be written Abichail. It was borne by several persons:
Abichail, the son of Huri, one of the family-chiefs of the tribe of Gad, who settled in Bashan ( 1 Chronicles 5:14).
Abichail, the father of Zuriel, who was the father of the Levitical tribes of Merari ( Numbers 3:35).
Abichail, the father of Queen Esther, and brother of Mordecai ( Esther 2:15).
