21:6 Let seven men of his {d} sons be delivered unto us, and we will hang them up {e} unto the LORD in Gibeah of Saul, [whom] the LORD did choose. And the king said, I will give [them].
(d) Of Saul's kinsmen.
(e) To pacify the Lord.
21:6 I will - Having doubtless consulted God in the matter; who as he had before declared Saul's bloody house to be the causes of this judgment, so now commanded that justice should be done upon it, and that the remaining branches of it should be cut off; as sufficiently appears from hence, that God was well pleased with the action; which he would not have been, if David had done it without his command; for then it had been a sinful action of David's, and contrary to a double law of God, Deut 21:23 24:16.
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.
