8 But the king took Armoni and Mephibosheth, the two sons of Saul to whom Rizpah, the daughter of Aiah, had given birth; and the five sons of Saul's daughter Merab, whose father was Adriel, the son of Barzillai the Meholathite: 9 And he gave them up to the Gibeonites, and they put them to death, hanging them on the mountain before the Lord; all seven came to their end together in the first days of the grain-cutting, at the start of the cutting of the barley.

10 And Rizpah, the daughter of Aiah, took haircloth, placing it on the rock as a bed for herself, from the start of the grain-cutting till rain came down on them from heaven; and she did not let the birds of the air come near them by day, or the beasts of the field by night. 11 And news was given to David of what Rizpah, the daughter of Aiah, one of Saul's wives, had done.

Commentary on 2 Samuel 21:1-9

(Read 2 Samuel 21:1-9)

Every affliction arises from sin, and should lead us to repent and humble ourselves before God; but some troubles especially show that they are sent to bring sin to remembrance. God's judgments often look a great way back, which requires us to do so, when we are under his rebukes. It is not for us to object against the people's smarting for the sin of their king; perhaps they helped him. Nor against this generation suffering for the sin of the last. God often visits the sins of the fathers upon the children, and he gives no account of any matters. Time does not wear out the guilt of sin; nor can we build hopes of escape upon the delay of judgments. If we cannot understand all the reasons of Providence in this matter, still we have no right to demand that God should acquaint us with those reasons. It must be right, because it is the will of God, and in the end it will be proved to be so. Money is no satisfaction for blood. It should seem, Saul's posterity trod in his steps, for it is called a bloody house. It was the spirit of the family, therefore they are justly reckoned with for his sin, as well as for their own. The Gibeonites did not require this out of malice against Saul or his family. It was not to gratify any revenge, but for the public good. They were put to death at the beginning of harvest; they were thus sacrificed to turn away the wrath of Almighty God, who had withheld the harvest-mercies for some years past, and to obtain his favour in the present harvest. In vain do we expect mercy from God, unless we do justice upon our sins. Executions must not be thought cruel, which are for the public welfare.

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.
