Several people have mentioned killing children but have not given specific biblical texts. Frankly, large numbers of Christians don't know much about the contents of their bible. Here are two examples of many.
Quote:Go and attack the Amalekites and completely destroy everything they have. Don't leave a thing; kill all the men, women, children, and babies; the cattle, sheep, camels, and donkeys. (1 Samuel 15:3)To be precise, the word translated "babies" means "nursing infants" in the Hebrew.
Quote:Babylon, you will be destroyed.The first six verses of this are much quoted (By the rivers of Babylon we sat down and wept ...) but not the conclusion.
Happy are those who pay you back
for what you have done to us—
who take your babies
and smash them against a rock. (Psalm 137:9)
