1 Samuel 25:14-17

14But one of the young men told Abigail, Nabal’s wife, saying, Behold, David sent messengers from the wilderness to greet our master; and he railed at them.1 15But the men were very good to us, and we were not hurt, neither missed we any thing, as long as we were conversant with them, when we were in the fields:2 16They were a wall to us both by night and day, all the while we were with them keeping the sheep. 17Now therefore know and consider what thou wilt do; for evil is determined against our master, and against all his household: for he is such a worthless man, that a man cannot speak to him.
