1 Samuel 11:15
And all the people went to Gilgal; and there they made Saul king before the LORD in Gilgal; and there they sacrificed sacrifices of peace offerings before the LORD; and there Saul and all the men of Israel rejoiced greatly. And all the people went to Gilgal; and there they made Saul king before the LORD in Gilgal; and there they sacrificed sacrifices of peace offerings before the LORD; and there Saul and all the men of Israel rejoiced greatly.
After his victory the kingship of Saul was solemnly confirmed in public before the Lord at Gilgal, with the people making him king there. That confirmation followed the deliverance of Jabesh-gilead from the Ammonites, which was God's work in giving Israel victory over the Ammonites. The occasion was kept with great rejoicing by Saul and all the men of Israel, and with sacrifices of peace offerings presented before the Lord. The recent victory had filled his army with hope and courage. Yet Saul afterward took the honor to himself and lost sight of his dependence on God, and that pride prepared the way for his later presumption and sacrilege at Gilgal.
