2 Samuel 21:14-18

Then they buried the bones of Saul and his son Jonathan in the country of Benjamin in Zela, in the grave of his father Kish; so they did everything that the king commanded, and after that God responded to prayer for the land.

Now when the Philistines were at war with Israel again, David went down, and his servants with him; and when they fought against the Philistines, David became weary.

Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels of bronze in weight, had strapped on a new sword, and he intended to kill David.

But Abishai the son of Zeruiah helped him, and struck the Philistine and killed him. Then David’s men swore to him, saying, “You shall not go out again with us to battle, so that you do not extinguish the lamp of Israel.”

Now it came about after this that there was war again with the Philistines at Gob; then Sibbecai the Hushathite struck and killed Saph, who was among the descendants of the giant.
