“Tell Aaron and his sons, ‘This is the way you are to bless the Israelites. Say to them:

Woe to you, Moab. You are ruined, O people of Chemosh! He has made his sons fugitives, and his daughters the prisoners of King Sihon of the Amorites.

So they defeated Og, his sons, and all his people, until there were no survivors, and they possessed his land.
