12 He then went and got the remains of Saul and Jonathan his son from the leaders at Jabesh Gilead (who had rescued them from the town square at Beth Shan where the Philistines had hung them after striking them down at Gilboa). 13 He gathered up their remains and brought them together with the dead bodies of the seven who had just been hanged. 14 The bodies were taken back to the land of Benjamin and given a decent burial in the tomb of Kish, Saul's father. They did everything the king ordered to be done. That cleared things up: from then on God responded to Israel's prayers for the land.

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.
