18 And it came to pass after this, that there was again a battle with the Philistines, at Gob; then Sibbechai the Hushathite smote Saph, who was of the children of Raphah. 19 And there was again a battle at Gob with the Philistines; and Elhanan the son of Jaare-oregim, a Bethlehemite, smote Goliath the Gittite; now the shaft of his spear was like a weaver's beam. 20 And there was again a battle, at Gath; and there was a man [there] of great stature, that had on each hand six fingers, and on each foot six toes, four and twenty in number; and he also was born to Raphah. 21 And he defied Israel; but Jonathan the son of Shimea David's brother smote him. 22 These four were born to Raphah, in Gath; and they fell by the hand of David, and by the hand of his servants.

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.
