2 Samuel 24:13-14, 25 (NLT)
So Gad came to David and asked him, "Will you choose three years of famine throughout your land, three months of fleeing from your enemies, or three days of severe plague throughout your land? Think this over and decide what answer I should give the LORD who sent me." "I'm in a desperate situation!" David replied to Gad. "But let us fall into the hands of the LORD, for his mercy is great. Do not let me fall into human hands."…David built an altar there to the LORD and sacrificed burnt offerings and peace offerings.
1 Samuel 26:7-11 (NLT)
So David and Abishai went right into Saul's camp and found him asleep, with his spear stuck in the ground beside his head. Abner and the soldiers were lying asleep around him.
"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!"
"No!" David said. "Don't kill him. For who can remain innocent after attacking the LORD's anointed one? Surely the LORD will strike Saul down someday, or he will die of old age or in battle.
