Ambi in the el-Amarna letters is apparently Moab or the capital of Moab. It is referred to together with Sigata (EA 76), that I recognized as Succoth on the Jordan. The same story of rebellion against Jerusalem is found in II Chronicles 20. The assault on Jerusalem did not materialize itself when (II Chronicles 20:23) the children of Ammon and Moab stood against the inhabitants of Mount Seir. Mount Seir is the land of Seeri of the letter 288.
