2 Samuel 23:17-19, 23

And he said, “Far be it from me, O LORD, that I should drink this. [Is it not the same as] the blood of the men who went at the risk of their lives?” So he would not drink it. These things the three mighty men did. Now Abishai the brother of Joab the son of Zeruiah was chief of the thirty. He wielded his spear against three hundred men and killed them, and gained a reputation beside the three. He was the most honored of the thirty, so he became their commander; however, he did not attain to the [greatness of the] three.

He was honored among the thirty, but he did not attain to the [greatness of the] three. David appointed him over his guard.
