8 "God has surely handed your enemy over to you this time!" Abishai whispered to David. "Let me pin him to the ground with one thrust of the spear; I won't need to strike twice!" 9 "No!" David said. "Don't kill him. For who can remain innocent after attacking the Lord 's anointed one? 10 Surely the Lord will strike Saul down someday, or he will die of old age or in battle.
Matthew Henry's Commentary on 1 Samuel 26:8-10
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.
