1 Samuel 15:29-31

New Century Version

²⁹ The Lord is the Eternal One of Israel. He does not lie or change his mind. He is not a human being, so he does not change his mind.”

³⁰ Saul answered, “I have sinned. But please honor me in front of the elders of my people and in front of the Israelites. Come back with me so that I can worship the Lord your God.” ³¹ So Samuel went back with Saul, and Saul worshiped the Lord.
