12 he went to the people of Jabesh-gilead and retrieved the bones of Saul and his son Jonathan. (When the Philistines had killed Saul and Jonathan on Mount Gilboa, the people of Jabesh-gilead stole their bodies from the public square of Beth-shan, where the Philistines had hung them.) 13 So David obtained the bones of Saul and Jonathan, as well as the bones of the men the Gibeonites had executed. 14 Then the king ordered that they bury the bones in the tomb of Kish, Saul's father, at the town of Zela in the land of Benjamin. After that, God ended the famine in the land.
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?"
18 After this, there was another battle against the Philistines at Gob. As they fought, Sibbecai from Hushah killed Saph, another descendant of the giants. 19 During another battle at Gob, Elhanan son of Jair from Bethlehem killed the brother of Goliath of Gath. The handle of his spear was as thick as a weaver's beam! 20 In another battle with the Philistines at Gath, they encountered a huge man with six fingers on each hand and six toes on each foot, twenty-four in all, who was also a descendant of the giants. 21 But when he defied and taunted Israel, he was killed by Jonathan, the son of David's brother Shimea. 22 These four Philistines were descendants of the giants of Gath, but David and his warriors killed them.

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.
