John Gill Commentary Ezekiel 40:26

"And there were seven steps to go up to it, and the arches thereof were before them; and it had palm-trees, one on this side, and another on that side, upon the posts thereof." — Ezekiel 40:26 (ASV)

And there were seven steps to go up to it
To the south gate, as there were to the east and north gates, (Ezekiel 40:6Ezekiel 40:42) : and the arches thereof were before them; (See Gill on Ezekiel 40:22): and it had palm trees, one on this side, and another on that side, upon
the posts thereof ;
that is, on the posts of this gate were palm trees, two on each post, one on one side, and the other on the other: this verse shows us how many palm trees were painted on the posts, and how they were disposed of; (See Gill on Ezekiel 40:16).
