1 Chronicles 2:15
Ozem the sixth, David the seventh; (ASV)
We read of Jesse that he had eight sons.
"Now David was the son of that Ephrathite of Bethlehem Judah, whose name was Jesse, and who had eight sons." (1 Samuel 17:12)
These eight sons are mentioned when Samuel was sent by God to annoint the successor to Saul from among Jesse's sons.
1 Samuel 16 1 Now the LORD said to Samuel, “How long will you mourn for Saul, seeing I have rejected him from reigning over Israel? Fill your horn with oil, and go; I am sending you to Jesse the Bethlehemite. For I have provided Myself a king among his sons.” 5 ...Then he consecrated Jesse and his sons, and invited them to the sacrifice. 6 ...he looked at Eliab and said, “Surely the LORD’S anointed is before Him.” 7 But the LORD said to Samuel, “Do not look at his appearance or at the height of his stature, because I have refused him. For the LORD does not see as man sees; for man looks at the outward appearance, but the LORD looks at the heart.” 8 So Jesse called Abinadab, and made him pass before Samuel. And he said, “Neither has the LORD chosen this one.” 9 Then Jesse made Shammah pass by. And he said, “Neither has the LORD chosen this one.” 10 Thus Jesse made seven of his sons pass before Samuel. And Samuel said to Jesse, “The LORD has not chosen these.” 11 And Samuel said to Jesse, “Are all the young men here?” Then he said, “There remains yet the youngest, and there he is, keeping the sheep.” And Samuel said to Jesse, “Send and bring him. For we will not sit down till he comes here.”
When we come to 1 Chronicles 2, we see only seven sons of Jesse listed.
"Jesse begot Eliab his firstborn, Abinadab the second, Shimea the third, Nethanel the fourth, Raddai the fifth, Ozem the sixth, and David the seventh." (1 Chronicles 2:13-15)
The genealogies listed in 1 Chronicles are not complete and the chronicler is not required either to provide complete genealogies or to explain the methodology he uses for those genealogies that he does provide. Bible commentators have speculated about the missing son. It could be that he had died. Perhaps he had no children and would not be listed. It could be that Jesse had two wives with seven sons by the one wife and one son by the second.
Later in 1 Chronicles we read of a brother of David named, Elihu.
"Furthermore, over the tribes of Israel: the officer over the Reubenites was Eliezer...over Judah, Elihu, one of David’s brothers;..." (1 Chronicles 27:16-18)
The Chronicler thus shows that he is aware of an eighth son of Jesse that he had not listed earlier. Some speculate that this was actually Eliab, the oldest of David's brothers but this cannot be proven.
The failure of the Chronicler to list all eight of the sons of Jesse proves neither contradiction or error. We can be perplexed about his rational for leaving one of the sons off the list, but nothing more.
