1 Samuel 15:33 WEB

³¹  So Samuel turned again after Saul; and Saul worshiped Yahweh.

³²  Then said Samuel, Bring you here to me Agag the king of the Amalekites. Agag came to him cheerfully. Agag said, Surely the bitterness of death is past.

³³  Samuel said, As your sword has made women childless, so shall your mother be childless among women. Samuel hewed Agag in pieces before Yahweh in Gilgal.

³⁴  Then Samuel went to Ramah; and Saul went up to his house to Gibeah of Saul.

³⁵  Samuel came no more to see Saul until the day of his death; for Samuel mourned for Saul: and Yahweh repented that he had made Saul king over Israel.
