12 Then David went and took the bones of Saul, and the bones of Jonathan his son, from the men of Jabesh Gilead who had stolen them from the street of Beth Shan, where the Philistines had hung them up, after the Philistines had struck down Saul in Gilboa. 13 So he brought up the bones of Saul and the bones of Jonathan his son from there; and they gathered the bones of those who had been hanged. 14 They buried the bones of Saul and Jonathan his son in the country of Benjamin in Zelah, in the tomb of Kish his father. So they performed all that the king commanded. And after that God heeded the prayer for the land.
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."
18 Now it happened afterward that there was again a battle with the Philistines at Gob. Then Sibbechai the Hushathite killed Saph, who was one of the sons of the giant. 19 Again there was war at Gob with the Philistines, where Elhanan the son of Jaare-Oregim the Bethlehemite killed the brother of Goliath the Gittite, the shaft of whose spear was like a weaver's beam. 20 Yet again there was war at Gath, where there was a man of great stature, who had six fingers on each hand and six toes on each foot, twenty-four in number; and he also was born to the giant. 21 So when he defied Israel, Jonathan the son of Shimea, David's brother, killed him. 22 These four were born to the giant in Gath, and fell by the hand of David and by the hand of his servants.

Commentary on 2 Samuel 21:10-14
(Read 2 Samuel 21:10-14)
That a guilty land should enjoy many years of plenty, calls for gratitude; and we need not wonder misused abundance should be punished with scarcity; yet how few are disposed to ask of the Lord concerning the sinful cause, while numbers search for the second causes by which he is pleased to work! But the Lord will plead the cause of those who cannot or will not avenge themselves; and the prayers of the poor are of great power. When God sent rain to water the earth, these bodies were buried, for then it appeared that God was entreated for the land. When justice is done on earth, vengeance from heaven ceases. God is pacified, and is entreated for us through Christ, who was hanged on a tree, and so made a curse for us, to do away our guilt, though he was himself guiltless.
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.
