8 And Abishai said to David, God has delivered thine enemy into thy hand this day; and now let me smite him, I pray thee, with the spear, even to the ground once, and I will not do it the second time. 9 And David said to Abishai, Destroy him not; for who can stretch forth his hand against Jehovah's anointed, and be guiltless? 10 And David said, [As] Jehovah liveth, Jehovah will surely smite him; either his day shall come to die, or he shall descend into battle and perish. 11 Jehovah forbid that I should stretch forth my hand against Jehovah's anointed! But now take, I pray thee, the spear that is at his head, and the cruse of water, and let us go.

Commentary on 1 Samuel 26:1-12
(Read 1 Samuel 26:1-12)
How soon do unholy hearts lose the good impressions convictions have made upon them! How helpless were Saul and all his men! All as though disarmed and chained, yet nothing is done to them; they are only asleep. How easily can God weaken the strongest, befool the wisest, and baffle the most watchful! David still resolved to wait till God thought fit to avenge him on Saul. He will by no means force his way to the promised crown by any wrong methods. The temptation was very strong; but if he yielded, he would sin against God, therefore he resisted the temptation, and trusted God with the event.
