Ezekiel 48:16

And this shall be the measures thereof
Of the city: the north side four thousand and five hundred;
that is, measures or reeds: the south side four thousand and five hundred, and on the east side
four thousand and five hundred, and the west side four thousand and
five hundred;
in all eighteen hundred measures or reeds, as in ( Ezekiel 48:35 ) which denotes the largeness of the Gospel church, especially in the latter day; when Jews and Gentiles will be converted, and multitudes, east, west, north and south, will be gathered to it; and as it is an equilateral square, this shows the perfection, firmness, stability, and duration of the church of Christ; so the holy city, the New Jerusalem, is for the same reasons said to be foursquare, ( Revelation 21:16 ) .
