1-а Самуїлова 15:33

But Samuel pronounced the sentence of death upon him: "As thy sword hath made women childless, so be thy mother childless before women!" מנּשׁים is to be understood as a comparative: more childless than (other) women, i.e., the most childless of women, namely, because her son was the king. From these words of Samuel, it is very evident that Agag had carried on his wars with great cruelty, and had therefore forfeited his life according to the lex talionis. Samuel then hewed him in pieces "before the Lord at Gilgal," i.e., before the altar of Jehovah there; for the slaying of Agag being the execution of the ban, was an act performed for the glory of God.

In this chapter we have the final rejection of Saul from being king, for his disobedience to God's command in not utterly destroying the Amalekites. By his wars and victories he hoped to magnify and perpetuate his own name and honour, but, by his mismanagement of them, he ruined himself, and laid his honour in the dust. Here is, I. The commission God gave him to destroy the Amalekites, with a command to do it utterly (Sa1 15:1-3). II. Saul's preparation for this expedition (Sa1 15:4-6). III. His success, and partial execution of this commission (Sa1 15:7-9). IV. His examination before Samuel, and sentence passed upon him, notwithstanding the many frivolous pleas he made to excuse himself (v. 10-31). V. The slaying of Agag (Sa1 15:32, Sa1 15:33). VI. Samuel's final farewell to Saul (Sa1 15:34, Sa1 15:35).
