Rashi, on Isa 16:2

“And it shall come to pass, that as a bird fleeing away, and as young ones flying out of the nest, so shall the daughters of Moab be in the passage of Arnon.”

“like a wandering bird from its nest. driven from the nest like young birds driven from their nest, who roam and wander, so shall the villages of Moab wander to the fords of the Arnon.”
