The Chronicler lists David as the seventh son of Jesse, while Samuel lists him as the eighth (1 Samuel 16:6–13; 17:12). Samuel does not mention the names of David’s fourth, fifth, or sixth brothers:
Nethanel
Raddai
Ozem
Later, the Chronicler mentions a brother named Elihu, who might have been an additional son (see study note on 1 Chronicles 27:18). The number seven, considered the “perfect” number, might symbolize that God chose David to rule.
