Ezekiel 40:18 Meaning and Commentary

Ezekiel 40:18

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.

Ezekiel 40:18 In-Context

16 and narrow windows [are] unto the little chambers, and unto their posts at the inside of the gate all round about -- and so to the arches -- and windows all round about [are] at the inside, and at the post [are] palm-trees.
17 And he bringeth me in unto the outer court, and lo, chambers and a pavement made for the court all round about -- thirty chambers on the pavement --
18 and the pavement unto the side of the gates over-against the length of the gates [is] the lower pavement;
19 and he measureth the breadth from before the lower gate, to the front of the inner court, on the outside, a hundred cubits, eastward and northward.
20 As to the gate of the outer court whose front [is] northward, he hath measured its length and its breadth;
