Isaiah 20:5-6

LXX2012(i) 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?
