Samuel
1 Samuel 9:9
(Beforetime in Israel, when a man went to enquire of God, thus he spake, Come, and let us go to the seer: for he that is now called a Prophet was beforetime called a Seer.)
Abner
1 Samuel 14:47-51
47
So Saul took the kingdom over Israel, and fought against all his enemies on every side, against Moab, and against the children of Ammon, and against Edom, and against the kings of Zobah, and against the Philistines: and whithersoever he turned himself, he vexed them.
48
And he gathered an host, and smote the Amalekites, and delivered Israel out of the hands of them that spoiled them.
49
Now the sons of Saul were Jonathan, and Ishui, and Melchishua: and the names of his two daughters were these; the name of the firstborn Merab, and the name of the younger Michal:
50
And the name of Saul's wife was Ahinoam, the daughter of Ahimaaz: and the name of the captain of his host was Abner, the son of Ner, Saul's uncle.
51
And Kish was the father of Saul; and Ner the father of Abner was the son of Abiel.
1 Samuel 17:55
And when Saul saw David go forth against the Philistine, he said unto Abner, the captain of the host, Abner, whose son is this youth? And Abner said, As thy soul liveth, O king, I cannot tell.
Joab
2 Samuel 10:9-14
9
When Joab saw that the front of the battle was against him before and behind, he chose of all the choice men of Israel, and put them in array against the Syrians:
10
And the rest of the people he delivered into the hand of Abishai his brother, that he might put them in array against the children of Ammon.
11
And he said, If the Syrians be too strong for me, then thou shalt help me: but if the children of Ammon be too strong for thee, then I will come and help thee.
12
Be of good courage, and let us play the men for our people, and for the cities of our God: and the LORD do that which seemeth him good.
13
And Joab drew nigh, and the people that were with him, unto the battle against the Syrians: and they fled before him.
14
And when the children of Ammon saw that the Syrians were fled, then fled they also before Abishai, and entered into the city. So Joab returned from the children of Ammon, and came to Jerusalem.
