1 Chronicles 2:13-15

Eliab Called also Elihu, 1 Chronicles 27:18, unless that was another son of Jesse, as some think, not mentioned elsewhere; which would make the number to be eight, according to 1 Samuel 16:10; 1 Samuel 17:12. Or that Elihu, although there called the brother of David, might perhaps only be his kinsman, according to the usual language of Scripture. David the seventh David was certainly the youngest son of Jesse, 1 Samuel 16:11. And if, as seems probable, one of them died soon after the time when they were said to he eight, he would of course be reckoned as the seventh.
