1 Chronicles 2:13-15 -

Give us what we have not elsewhere, the names of the fourth, fifth, and sixth sons of Jesse, viz. Nathaneel, Raddai (but see 1 Kings 1:8 ), and Ozem . But, on the other hand, they make it appear that David was the seventh of seven, instead of ( 1 Samuel 14:10 , 1 Samuel 14:11 ; 1 Samuel 17:12 ) the eighth of eight sons. The missing son, any way, belongs to the seventh place. The Syriac and Arabic versions have taken the Elihu of 1 Chronicles 27:18 , and put him in this place. Others, following the Septuagint, suppose this Elihu, if strictly a brother of David, to be Eliab, the oldest. The explanation of the absence of the name here may be that he died early and without issue, and would accordingly be the less wanted in a genealogical register.
