They that are far off — This verse hath a double reference, one to the Jews, and the building of the material temple, the other to the bringing in of the Gentiles. And this — The literal part shall come to pass in your day, if you will obey the voice of the Lord. The mystical part shall come to pass also, and, if you will believe and obey, the Gentiles shall come in and be your brethren, and help to build the temple, the spiritual temple. But if you rebel and obey not, you shall be cast out and the Gentiles be taken in, to be God's people.
