2 Samuel 21:1-3

1There was famine in the days of David for three consecutive years; and David sought the presence (face) of the Lord [asking the reason]. The Lord replied, “It is because of Saul and his bloody house, because he put the Gibeonites to death.”

2So the king called the Gibeonites and spoke to them (now the Gibeonites were not of the sons (descendants) of Israel but of the remnant (survivors) of the Amorites. The Israelites had sworn [an oath] to [spare] them, but Saul in his zeal for the sons of Israel and Judah had sought to strike down the Gibeonites).

3So David said to the Gibeonites, “What should I do for you? How can I make it good so that you will bless the Lord’s inheritance (Israel)?”
