2 Kings 3:27

Then he, the king of Moab, took his eldest son that should have reigned in his stead, the heir apparent to the throne, and offered him for a burnt offering upon the wall, sacrificing him to the Moabite war-god Chemosh in full sight of the besieging army. And there was great indignation against Israel, their army was filled with disgust and indignation at this deed; and they departed from him, not wishing to remain any longer in that country, horrified at seeing this human sacrifice, and returned to their own land. Thus all believers should abhor the abominations of the idolatrous world and flee from their temptations.
