In the Tabernacle, as later in the Temple, gold, silver, and brass were employed, but not iron. God meant to indicate by the exclusion of iron that "in the future time," "the golden Babylon, the silver Media, and the brazen Greece," would be permitted to bestow the gifts on the new Temple, but not "the iron Rome." It is true that Babylon also destroyed the sanctuary of God, like Rome, but not with such fury and such thorough-going wrath as Rome, whose sons cried: "Raze it, raze it, even to the foundations thereof," and for this reason Rome may not contribute to the Messianic Temple.
And as God will reject the gifts of Rome, so also will the Messiah, to whom all the nations of the earth will have to offer gifts. Egypt will come with her gifts, and although the Messiah will at first refuse to accept anything from the former taskmaster of Israel, God will say to him: "The Egyptians granted My children an abode in their land, do not repulse them." Then the Messiah will accept their gift.
After Egypt will follow her neighbor, Ethiopia, with her gifts, thinking that if the Messiah accepted gifts from the former taskmaster of Israel, he will also accept gifts from her. Then the Messiah will also accept Ethiopia's gifts. After these two kingdoms will follow all others with their gifts, and all will be accepted save those from Rome. This kingdom will be sorely disappointed, for, depending upon their kinship with Israel, they will expect kind treatment from the Messiah, who had graciously received the other nations not connected with Israel.
But God will call out to the Messiah: "Roar at this monster that devours the fat of nations, that justifies its claims for recognition through being a descendant of Abraham by his grandson Esau, the nation that forgives all for the sake of money, that kept Israel back from the study of the Torah, and tempted them to deeps that are in accord with the wishes of Satan."
