And Samuel saith unto Saul, 'Thou hast been foolish; thou hast not kept the command of Jehovah thy God, which He commanded thee, for now had Jehovah established thy kingdom over Israel unto the age; read more.
and, now, thy kingdom doth not stand, Jehovah hath sought for Himself a man according to His own heart, and Jehovah chargeth him for leader over His people, for thou hast not kept that which Jehovah commanded thee.'
