1 Samuel 15:28,29

The Lord hath rent the kingdom from thee Hath declared his firm resolution of laying aside thy family, and will soon actually take away thy life and thy kingly power. Also the Strength of Israel Who is perfectly able to bring to pass all his purposes, and to make good all his declarations; will not lie He gives God his title, to show the reason why he neither can nor will lie. For lying generally proceeds from a man's weakness and inability to accomplish his designs, as he thinks, without it. But God needs no such artifices: he can do whatsoever he pleaseth by his absolute power. Nor repent Change his counsel and purpose, which is also an effect of weakness and imperfection, either of wisdom or power. So that this word is not here used in the sense it is 1 Samuel 15:11, and in several other passages, as Genesis 6:6; Exo 32:14; 2 Samuel 24:16; Jeremiah 26:19; in all which, and many others, it signifies a change of God's proceedings, and of his method of dealing with persons.
