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."
15 Moreover the Philistines had yet war again with Israel; and David went down, and his servants with him, and fought against the Philistines: and David waxed faint. 16 And Ishbibenob, which was of the sons of the giant,
15 There was war again between the Philistines and Israel, and David went down together with his servants, and they fought against the Philistines. And David grew weary. 16 And Ishbi-benob, one of the descendants of the giants, whose spear weighed three hundred shekels
15 War broke out again between the Philistines and Israel. David and his men went down to fight. David became exhausted. 16 Ishbi-Benob, a warrior descended from Rapha, with a spear weighing nearly eight pounds and outfitted in brand-new armor, announced that he'd kill David. 17 But Abishai son of Zeruiah came to the rescue, struck the Philistine, and killed him. Then David's men swore to him, "No more fighting on the front-lines for you! Don't snuff out the lamp of Israel!"
15 When the Philistines were at war again with Israel, David and his servants with him went down and fought against the Philistines; and David grew faint. 16 Then Ishbi-Benob, who was one of the sons of the giant, the weight of whose bronze spear was three hundred shekels, who was bearing a new sword, thought he could kill David. 17 But Abishai the son of Zeruiah came to his aid, and struck the Philistine and killed him. Then the men of David swore to him, saying, "You shall go out no more with us to battle, lest you quench the lamp of Israel."
15 Once again the Philistines were at war with Israel. And when David and his men were in the thick of battle, David became weak and exhausted. 16 Ishbi-benob was a descendant of the giants ; his bronze spearhead weighed more than seven pounds, and he was armed with a new sword. He had cornered David and was about to kill him. 17 But Abishai son of Zeruiah came to David's rescue and killed the Philistine. Then David's men declared, "You are not going out to battle with us again! Why risk snuffing out the light of Israel?"

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.
