2 Chronicles 11:18
And Rehoboam took him Mahalath the daughter of Jerimoth the son of David to wife, and Abihail the daughter of Eliab the son of Jesse; (2 Chronicles 11:18)
Jerimoth.
 He is not elsewhere named among the sons of David’s wives (2 Sam. 3:2-5; 5:14-16; 1 Chron. 3:1-9; 14:4-7). But he may have been the son of one of David’s concubines (1 Chron. 3:9).
Daughter of Eliab.
 Probably the granddaughter. The Hebrew word for daughter may also stand for more distant descendants (see on 1 Chron. 2:7). The daughter of David’s eldest brother (1 Sam. 17:13) could hardly have become the wife of David’s grandson.
