A famine hit the land of Israel. At first, David thought it was a natural event until it lasted for three years. He then realized the famine was from God. So he asked the Lord about it. God said, “It is because of what Saul did to the Gibeonites.”

The Tabernacle of God was at Gibeon. The Ark of God was in Jerusalem, but the Tabernacle was set up in Gibeon. So there were two places of worship.
