1st Samuel 15:30

27 And when Samuel was turning round to go away, Saul took the skirt of his robe in his hand, and the cloth came away.

28 And Samuel said to him, The Lord has taken away the kingdom of Israel from you this day by force, and has given it to a neighbour of yours who is better than you.

29 And further, the Glory of Israel will not say what is false, and his purpose may not be changed: for he is not a man, whose purpose may be changed.

30 Then he said, Great is my sin: but still, give me honour now before the heads of my people and before Israel, and come back with me so that I may give worship to the Lord your God.

31 So Samuel went back after Saul, and Saul gave worship to the Lord.

32 Then Samuel said, Make Agag, the king of the Amalekites, come here to me. And Agag came to him shaking with fear. And Agag said, Truly the pain of death is past.

33 And Samuel said, As your sword has made women without children, so now your mother will be without children among women. And Agag was cut up by Samuel, bone from bone, before the Lord in Gilgal.
