Isaiah 45:14

Thus saith the Lord, in foretelling the overthrow of the Gentiles everywhere, The labor of Egypt, that which the Egyptians had gained by their labor, and merchandise of Ethiopia, what the Ethiopians gathered by their commercial activities, and of the Sabeans, men of stature, the inhabitants of Meroe in Upper Egypt being known far and wide on account of their great size, shall come over unto thee, and they shall be thine, freely submitting themselves; they shall come after thee, in chains they shall come over, as though bound hand and foot, and they shall fall down unto thee, acknowledging Israel as their superior, they shall make supplication unto thee, saying, Surely God is in thee, and there is none else, there is no (other true) God. Israel is here declared to be the nation of the one true God.
