Re 16:19
and shall be exalted above the hills; Mount Zion is above Mount Sinai, or the Gospel dispensation is preferable to the legal one. It is an observation of Jarchi, that it shall be exalted by a greater sign or miracle that shall be done in it than was done in Sinai, Carmel, and Tabor; the law was given on Sinai, and many wonders wrought; but on Zion the Messiah himself appeared, and his Gospel was published, and miracles wrought by him. And in the latter day, when Christ, and he alone, shall be exalted, as he will at the time this prophecy refers to, Isa 2:11 the church will be exalted; the glory of the Lord will be risen upon her; the interest of Christ will exceed all other interests; his religion will be the prevailing one; the kingdoms of this world will become his; and his dominion will be from sea to sea, and from the rivers to the end of the earth. This may also denote the visibility of the kingdom and church of Christ; it will be as a city on a hill; and however obscure the church is now, being in the wilderness, it will at this time be visible to all:
and all nations shall flow unto it; that is, many out of all nations shall be converted, and come freely and willingly to join themselves to the church of Christ; they shall come in great numbers, in company together, and that continually, like flowing streams; they shall first flow to the Lord, and to his goodness, and then to his church and ordinances; see Isa 60:4.
