Isaiah 20:5-6. “And they shall be afraid and ashamed of Ethiopia their expectation, and of Egypt their glory. And the inhabitant of this isle shall say in that day Behold, such is our expectation, whither we flee for help to be delivered from the king of Assyria: and how shall we escape?”
Israel chose her sin; the nation turned from God to worship the idols of the surrounding people. The consequence, of which they were warned many times, was the be conquered and subjugated to Assyria. The could not escape.
The ones they had depended upon for help could not help them. Ethiopia had been their hope, and it fell to Assyria. Egypt had been the glory of escape, and it fell to Assyria.
This isle refers to all of Palestine, which also came under the devastating invasion of Assyria.
There are those in America today who are warning of the consequences of our having forsaken God. We will not get to choose the consequences for our sin. I wonder how many of us listen, but do not hear.
