NET
4 David’s men said to him, “This is the day about which the Lord said to you, ‘I will give your enemy into your hand, and you can do to him whatever seems appropriate to you.’” So David got up and quietly cut off an edge of Saul’s robe.
Darby
4 And David's men said to him, Behold the day of which Jehovah said to thee, Behold, I will give thine enemy into thy hand, that thou mayest do to him as it shall seem good to thee. And David arose, and cut off the skirt of Saul's robe secretly.
