2 Samuel 21:7-10

7But 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.

8So 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;

9and 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.

10Now Rizpah the daughter of Aiah took sackcloth and spread it for herself on the rock, from the beginning of harvest until the late rains poured on them from heaven. And she did not allow the birds of the air to rest on them by day nor the beasts of the field by night.
