1 Samuel 13:12-14

King James Version

¹² Therefore said I, The Philistines will come down now upon me to Gilgal, and I have not made supplication unto the Lord: I forced myself therefore, and offered a burnt offering.

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

¹⁴ But now thy kingdom shall not continue: the Lord hath sought him a man after his own heart, and the Lord hath commanded him to be captain over his people, because thou hast not kept that which the Lord commanded thee.
