Who defeated Midian in the country of Moab: that is, “who defeated the people of Midian in a battle in the country of Moab.” In some languages it is necessary to say “Hadad went to the country of Moab and fought with the Midianites there and defeated them.” This may be a separate sentence at the end of the verse.
