2 Kings 3:27

He took his eldest son and offered him for a burnt-offering upon the walls “Not only the Holy Scriptures, but several heathen writers assure us, that in case of great extremity, it was customary among various people to sacrifice to their gods whatever was most dear to them.” Eusebius and Luctantius mention several nations who used these sacrifices. And “Cesar, in his war with the Gauls, tells us that when they were afflicted with grievous diseases, or in time of war or great danger, they either offered men for sacrifices, or vowed that they would offer them; because they imagined that their gods could never be appeased unless one man's life was given for another's. In conformity with this horrid custom, and to appease, no doubt, as he thought, the anger of his idol Chemosh, the king of Moab made this costly sacrifice of his eldest son; a deed which, it is plain from the text, was held in the greatest abhorrence by the Israelites.” Dodd. For so, it seems, we are to understand the following words, which should be rendered, not, There was great indignation against Israel, but, There was great trouble, or repentance upon (in or among) Israel: that is, they were extremely grieved on account of this barbarous sacrifice, and wished they had not pushed on a war so far, which ended in such a horrid action. They departed from him, and returned to their own land They resolved to prosecute the war no further; but raised the siege, by common consent, and returned home, for fear any such thing should be done again.
