'Your Enemy' in the Bible

And the men of David said to him, Behold, this is the day of which Jehovah said to you, Behold, I will deliver your enemy into your hand so that you may do to him as it shall seem good to you. And David arose and cut off the skirt of Saul's robe secretly.

And Abishai said to David, God has shut up your enemy into your hand this day. And please let me strike him with the spear even to the earth at once, and I will not repeat it to him.

And Samuel said, Why then do you ask me, since Jehovah has left you and has become your enemy?
