Why is there a difference in the number of sons of Jesse in 1 Samuel & 1 Chronicles
1 Samuel 16:10-11 Jesse had seven of his sons pass by Samuel. But Samuel said to him, "The LORD has not chosen any of these." 11 Then he asked Jesse, "Are these all the sons you have?" Jesse answered, "I still have the youngest son. (David) He is out taking care of the sheep."
1 Chronicles 2:13 Jesse was the father of Eliab his firstborn; the second son was Abinadab, the third Shimea, 14 the fourth Nethanel, the fifth Raddai, 15 the sixth Ozem and the seventh David.
