John Gill's Bible Commentary Ver. 9. And David said to Abishai, destroy him not , etc.] He laid his commands upon him not to hurt him: for who can stretch forth his hand against the Lord’s anointed, and be guiltless ? since Saul was king, and appointed to that office by the Lord, and was anointed by his order for it, and invested with it by him, his person was sacred, and not to be touched; nor could his life be taken away by any without being guilty of a very great crime indeed, which it might be justly expected the Lord would resent and punish.
Matthew Henry Commentary
Verses 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 thoug disarmed and chained, yet nothing is done to them; they are onl asleep. How easily can God weaken the strongest, befool the wisest, an baffle the most watchful! David still resolved to wait till God though 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.
