18 The pavement was by the side of the gates, answerable to the length of the gates, even the lower pavement.
*Minor differences ignored. Grouped by changes, with first version listed as example.
And the pavement by the sides of the gates over against the length of the gates was the lower pavement. That is, this pavement, which went along by every gate, and answered the length of them, and what appertained to them, east, west, north, and south, was either lower than the pavement in the inward court, adjoining to this, to which there was an ascent by steps; or the middle part of this pavement rose up in a convex form, and on all sides there was a declivity; by which means all filth was washed away, and it was kept clean, and always fit to walk on. This distinction of a higher and lower pavement, whether on one account or another, may point out; the one, the believer's walk by faith on Christ; and the other, his walk in the ordinances of Christ, and in all becoming conversation.
The higher pavement was level with the entrance of the gates, the lower was on either side of the raised pavement thus formed. Whereas Solomon's temple had an outer court open to alterations and even idolatrous innovations (2-Kings 23:11-12; 1-Chronicles 20:5), in this there was to be no room for human corruptions. Its compass was exactly defined, one hundred cubits; and the fine pavement implied it was to be trodden only by clean feet (compare Isaiah 35:8).
The pavement - That mentioned, Ezekiel 40:17. By the side - That part which lay on each side of the gate, and from thence spread itself toward the chambers, leaving a space of pavement of equal breadth with the porch, or gate in the middle. The length - The length was measured fifty cubits. The inner pavement - The side pavement was laid somewhat lower than this middle pavement, not only for state, but for the more convenient, keeping it clean; so the middle pavement rose with a little convex surface.
