Matthew Poole and continuators on 1 Samuel 15:29

29 And also the strength of Israel will not lie k, nor repent : for he is not a man that he should repent.

So he calls God here; partly, to shew the reason why God neither will nor can lye; because lying is a weakness, and proceeds from the sence of a Mans weakness, because he cannot many times accomplish his Design without lying and dissimulation; which therefore many Princes have used for this very reason. But, saith he, God needs no such Artifices; he can do whatsoever he pleaseth by his Absolute Power, and hath no need to use lyes to accomplish his Will: partly, to shew that Israel should be no loser by Saul's loss, as he might vainly imagine, because he had saved them from their Enemies on every side, chap. 14. 47. For not Saul, but God, was the Strength and Protector of Israel, and he would continue to save them when Saul was lost and gone: and partly, to assure Saul that God would Execute this Threatning, because he wanted not strength to do it, and none could hinder him in it.

i. e. Nor ehange his Counsel; which also is an effect of weakness and imperfection, either of Wisdom or Power.
