1 Samuel 13:8-14

8Now Saul waited seven days, according to the appointed time which Samuel had set, but Samuel had not come to Gilgal; and the people were scattering away from Saul.

9So Saul said, “Bring me the burnt offering and the peace offerings.” And he offered the burnt offering [which he was forbidden to do].

10As soon as he finished offering the burnt offering, Samuel finally came; Saul went out to meet and to welcome him.

11But Samuel said, “What have you done?” Saul said, “Since I saw that the people were scattering away from me, and that you did not come within the appointed time, and that the Philistines were assembling at Michmash,

12therefore, I said, ‘Now the Philistines will come down against me at Gilgal, and I have not asked for the Lord’s favor [by making supplication to Him].’ So I forced myself to offer the burnt offering.”

13Samuel said to Saul, “You have acted foolishly; you have not kept the commandment of the Lord your God, which He commanded you, for [if you had obeyed] the Lord would have established your kingdom over Israel forever.

14But now your kingdom shall not endure. The Lord has sought out for Himself a man (David) after His own heart, and the Lord has appointed him as leader and ruler over His people, because you have not kept (obeyed) what the Lord commanded you.”
