2 Samuel 21:7 Meaning and Commentary

2 Samuel 21:7

But the king spared Mephibosheth, the son of Jonathan, the son
of Saul
As they did not name particular persons, only required seven sons, it was at the option of the king what sons to deliver to them, and therefore kept back Mephibosheth, who is thus described, to distinguish him from a son of Saul's of the same name, after mentioned:

because of the Lord's oath that [was] between them, between David and
Jonathan the son of Saul;
not merely or only out of affection to Mephibosheth, but because of the oath, that he might not be guilty of the same crime Saul was in slaying the Gibeonites.

2 Samuel 21:7 In-Context

5 Then they answered the king, "As for the man who consumed us and plotted against us, that we should be destroyed from remaining in any of the territories of Israel,

6 let seven men of his descendants be delivered to us, and we will hang them before the Lord in Gibeah of Saul, whom the Lord chose." And the king said, "I will give them."

7 But the king spared Mephibosheth the son of Jonathan, the son of Saul, because of the Lord's oath that was between them, between David and Jonathan the son of Saul.

8 So the king took Armoni and Mephibosheth, the two sons of Rizpah the daughter of Aiah, whom she bore to Saul; and the five sons of Michal the daughter of Saul, whom she brought up for Adriel the son of Barzillai the Meholathite;

9 and he delivered them into the hands of the Gibeonites, and they hanged them on the hill before the Lord. So they fell, all seven together, and were put to death in the days of harvest, in the first days, in the beginning of barley harvest.
