2 Samuel 21:6

2 At this, David summoned the Gibeonites and spoke to them. (Now the Gibeonites were not Israelites, but a remnant of the Amorites. The Israelites had taken an oath concerning them, but in his zeal for Israel and Judah, Saul had sought to kill them.)

3 So David asked the Gibeonites, “What shall I do for you? How can I make amends so that you may bless the inheritance of the LORD?”

4 The Gibeonites said to him, “We need no silver or gold from Saul or his house, nor should you put to death anyone in Israel for us.” “Whatever you ask, I will do for you,” he replied.

5 And they answered the king, “As for the man who consumed us and plotted against us to exterminate us from existing within any border of Israel,

6 let seven of his male descendants be delivered to us so that we may hang them before the LORD at Gibeah of Saul, the chosen of the LORD.” “I will give them to you,” said the king.

7 Now the king spared Mephibosheth son of Jonathan, the son of Saul, because of the oath before the LORD between David and Jonathan son of Saul.

8 But the king took Armoni and Mephibosheth, the two sons whom Rizpah daughter of Aiah had borne to Saul, as well as the five sons whom Merab daughter of Saul had borne to Adriel 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 all seven of them fell together; they were put to death in the first days of the harvest, at the beginning of the barley harvest.

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