'Your Enemy' in the Bible

The men of David said to him, "Behold, the day of which the LORD said to you, 'Behold, I will deliver your enemy into your hand, and you shall do to him as it shall seem good to you.'" Then David arose, and cut off the skirt of Saul's robe secretly.

Then Abishai said to David, "God has delivered up your enemy into your hand this day. Now therefore please let me strike him with the spear to the earth at one stroke, and I will not strike him the second time."
