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.
Oh, he didn't fear the people. Again he's just offering a lame excuse for his disobedience. God would rather have just a straight, frank confession. "God, I blew it. I was wrong. I sinned. God, I'm sorry, I repent." God wants-there's no sign of repentance in this at all. Some people think it's cute to say, "Oh, I'm a sinner." That isn't repentance, it's only a declaration of a blasphemous truth. "Oh, I sinned." Doesn't make anything out of you, forsaking the sin is what is important. Turning from the sin, the repentance is what God is seeking.
