Commentary on 1 Samuel 26:1-12

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.
