8 And the king took the two sons of Rizpah the daughter of Aiah, whom she had borne to Saul, Armoni and Mephibosheth; and the five sons of [the sister of] Michal the daughter of Saul, whom she had borne to Adriel the son of Barzillai the Meholathite; 9 and he gave them into the hands of the Gibeonites, and they hanged them on the hill before Jehovah. And they fell all seven together, and were put to death in the first days of the harvest, in the beginning of barley harvest.

10 Then Rizpah the daughter of Aiah took sackcloth, and spread it for her upon the rock, from the beginning of harvest until water poured on them out of the heavens, and suffered neither the fowl of the heavens to rest on them by day, nor the beasts of the field by night. 11 And it was told David what Rizpah the daughter of Aiah, the concubine of Saul, 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.
