Abishai Rescues David from the Giant

15 Once again there was a battle between the Philistines and Israel. David went down with his men to fight against the Philistines, and he became exhausted. 16 And Ishbi-Benob, one of the descendants of Rapha, whose bronze spearhead weighed three hundred shekels[1] and who was armed with a new sword, said he would kill David. 17 But Abishai son of Zeruiah came to David's rescue; he struck the Philistine down and killed him. Then David's men swore to him, saying, "Never again will you go out with us to battle, so that the lamp of Israel will not be extinguished."

The Giants Slain by David's Men

18 In the course of time, there was another battle with the Philistines, at Gob. At that time Sibbekai the Hushathite killed Saph, one of the descendants of Rapha. 19 In another battle with the Philistines at Gob, Elhanan son of Jair[2] the Bethlehemite killed the brother of[3] Goliath the Gittite, who had a spear with a shaft like a weaver's rod. 20 In still another battle, which took place at Gath, there was a huge man with six fingers on each hand and six toes on each foot-twenty-four in all. He also was descended from Rapha. 21 When he taunted Israel, Jonathan son of Shimeah, David's brother, killed him. 22 These four were descendants of Rapha in Gath, and they fell at the hands of David and his men.

Commentary on 2 Samuel 21:15-22

(Read 2 Samuel 21:15-22)

These events seem to have taken place towards the end of David's reign. David fainted, but he did not flee, and God sent help in the time of need. In spiritual conflicts, even strong saints sometimes wax faint; then Satan attacks them furiously; but those who stand their ground and resist him, shall be relieved and made more than conquerors. Death is a Christian's last enemy, and a son of Anak; but through Him that triumphed for us, believers shall be more than conquerors at last, even over that enemy.
