Over a hundred years before Isaiah’s time, the nation of Moab, distantly related to the Israelites (Genesis 19), had expanded their territory northward across the Arnon River into area formerly belonging to Israel. This may have led to the pride for which Isaiah condemned them. He foretold of the doom that awaited them in three years (Isa. 16:14), perhaps carried out by the Assyrians during their invasion of the nation.
