1 Samuel 13:11-15

11And Samuel said, What hast thou done? And Saul said, Because I saw that the people were scattered from me, and that thou didst not come within the days appointed, and that the Philistines were assembled at Michmash,

12I said, The Philistines will come down now upon me to Gilgal, and I have not made supplication to Jehovah; and I forced myself, and offered up the burnt-offering.

13And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of Jehovah thy 1God which he commanded thee; for now would Jehovah have established thy kingdom over Israel for ever.

14But now thy kingdom shall not continue: Jehovah has sought him a man after his own heart, and Jehovah has appointed him ruler over his people; for thou hast not kept what Jehovah commanded thee.

15And Samuel arose and went up from Gilgal to Gibeah of Benjamin. And Saul numbered the people that were found with him, about six hundred men.
