Melachim Bais 3:26-27

Orthodox Jewish Bible

²⁶ And when Melech Moav saw that the milchamah was chazak against him, he took with him 700 ish that drew cherev, to break through even unto Melech Edom; but they could not.

²⁷ Then he took bno habechor that should have reigned in his stead, and offered him for an olah upon the chomah. And there was ketzef gadol (great fury) against Yisroel; and they withdrew, and returned to their own land.
