2 Kings 3:27

But when he could not, he took his son, his first-born, whom he had made king in his stead, and offered him up as a whole burnt offering on the walls. Upon which great commiseration came upon Israel, and they departed from him, and returned into their own land.

And he took his eldest son whom he had designed to reign in his stead, and offered him up for a whole-burnt-offering on the walls. And there was a great indignation against Israel; and they departed from him, and returned to their land.
