Shmuel Alef 13:8-14

And he tarried shivat yamim, according to the mo'ed (set time) that Shmuel had appointed; but Shmuel came not to Gilgal; and HaAm started slipping away from him. And Sha'ul said, Bring to me the olah (burnt offering), and shelamim (peace offerings). And he offered the olah (burnt offering). And it came to pass, that as soon as he had finished offering the olah (burnt offering), hinei, Shmuel came; and Sha'ul went out to meet him, that he might make a brocha greeting on him. And Shmuel said, What hast thou done? And Sha'ul said, Because I saw that HaAm were slipping away from me, and that thou camest not at the mo'ed hayamim, and that the Pelishtim were assembling themselves together at Michmas; Therefore, said I, the Pelishtim (Philistines) will come down now upon me at Gilgal, and I have not made supplication unto HASHEM; I felt compelled therefore, and offered the olah (burnt offering). And Shmuel said to Sha'ul, Thou hast done foolishly; thou hast not been shomer over the mitzvat HASHEM Eloheicha, which He commanded thee; for now would HASHEM have established thy mamlachah over Yisroel ad olam. But now thy mamlachah shall not endure; HASHEM hath sought for Him an ish after His own levav, and HASHEM hath commanded him to be Nagid over His people, because thou hast not been shomer over that which HASHEM commanded thee.
