Esias 20:6 In-Context

4 for thus shall the king of the Assyrians lead the captivity of Egypt and the Ethiopians, young men and old, naked and barefoot, having the shame of Egypt exposed.
5 And the Egyptians being defeated shall be ashamed of the Ethiopians, in whom they had trusted; for they were their glory.
6 And they that dwell in this island shall say in that day, Behold, we trusted to flee to them for help, who could not save themselves from the king of the Assyrians: and how shall we be saved?
