And in this mountain In mount Zion, namely, God's church, very frequently meant by the names of Zion and Jerusalem, both in the Old and New Testaments; shall the Lord make unto all people Both Jews and Gentiles, who shall then be admitted to a participation of the same privileges and ordinances; a feast of fat things A feast made of the most delicate provisions: which is manifestly meant of the ordinances, graces, and comforts given by God in his church. Of wines on the lees Which have continued upon the lees a competent time, whereby they gain strength, and are afterward drawn out and refined. He will destroy the face of the covering The covering of the face, or the veil, as the next clause expounds it, namely, of ignorance of God, and of the true religion; cast over all people Which then was upon the Gentiles and the Jews, 2 Corinthians 3:14-16. This is a manifest prophecy concerning the illumination and conversion of the Gentiles.
