The LORD causes the poor Moabites to be killed; scorchs the earth, drives the King sacrifice his son. But hey, It's but a "light thing".
3:18 And this is but a light thing in the sight of the LORD: he will deliver the Moabites also into your hand.
3:19 And ye shall smite every fenced city, and every choice city, and shall fell every good tree, and stop all wells of water, and mar every good piece of land with stones.
(What a great idea - destroy everything - make the place uninhabitable - gawd is good, gawd is great)
3:24 And when they came to the camp of Israel, the Israelites rose up and smote the Moabites, so that they fled before them: but they went forward smiting the Moabites, even in their country.
3:25 And they beat down the cities, and on every good piece of land cast every man his stone, and filled it; and they stopped all the wells of water, and felled all the good trees: only in Kirharaseth left they the stones thereof; howbeit the slingers went about it, and smote it.
3:26 And when the king of Moab saw that the battle was too sore for him, he took with him seven hundred men that drew swords, to break through even unto the king of Edom: but they could not.
3:27 Then he took his eldest son that should have reigned in his stead, and offered him for a burnt offering upon the wall. And there was great indignation against Israel: and they departed from him, and returned to their own land.
Hey... when did gawd think of "turn the other cheek"?
