Charles Ellicott Commentary Isaiah 45:14

"Thus saith Jehovah, The labor of Egypt, and the merchandise of Ethiopia, and the Sabeans, men of stature, shall come over unto thee, and they shall be thine: they shall go after thee, in chains they shall come over; and they shall fall down unto thee, they shall make supplication unto thee, [saying], Surely God is in thee; and there is none else, there is no God." — Isaiah 45:14 (ASV)

Thus says the Lord ... —A new section opens. In Isaiah 43:3, Egypt, Ethiopia, Seba, had been given to Cyrus, as a reward, or ransom, for the deliverance of Israel. Here the prophet goes a step further, and contemplates them as coming, in the spirit of a voluntary surrender, as proselytes to the faith of Israel, in self-imposed bondage, offering to Israel, as one with God, the "supplication" which, elsewhere, is offered to Jehovah.

The promise reminds us of Psalm 68:31; Psalms 72:10, and yet more of Isaiah 19:23; Isaiah 9:5–7. A partial fulfilment may have been found in the command given by Cyrus, that these and other nations should assist in the work of rebuilding the Temple (Ezra 1:4). Egypt and Ethiopia send the products of their labour. The Sabeans (that is to say, the people of Meroe), strong, but not wealthy, come freely to offer their own labour.
