Parallel
Isaiah 19:20
Brenton's English Septuagint · Berean Standard Bible
And it shall be for a sign to the Lord for ever in the land of Egypt: for they shall presently cry to the Lord by reason of them that afflict them, and he shall send them a man who shall save them; he shall judge and save them.
It will be a sign and a witness to the LORD of Hosts in the land of Egypt. When they cry out to the LORD because of their oppressors, He will send them a savior and defender to rescue them.
