2 Kings 3:25-27

25They destroyed the [walls of the] cities, and each man threw a stone on every piece of good land, covering it [with stones]. And they stopped up all the springs of water and cut down all the good trees, until they left nothing in Kir-hareseth [Moab’s capital city] but its stones. Then the [stone] slingers surrounded the city and destroyed it.

26When the king of Moab saw that the battle was too fierce for him, he took with him seven hundred swordsmen to break through to the king of Edom; but they could not.

27Then the king of Moab took his eldest son, who was to reign in his place, and offered him [publicly] as a burnt offering [to Chemosh] on the [city] wall [horrifying everyone]. And there was great wrath against Israel, and Israel’s allies [Judah and Edom] withdrew from King Jehoram and returned to their own land.
