The men of David said to him, Behold, the day of which Yahweh 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.
and cut off the skirt of Saul's robe privily; unawares to him, and unobserved by him, which might be easily done, if Saul was asleep, and it is probable he was; and by the same way it may be accounted for that he did not hear the discourse that passed between David and his men.
