John Gill Commentary Ezekiel 10:15

"And the cherubim mounted up: this is the living creature that I saw by the river Chebar." — Ezekiel 10:15 (ASV)

And the cherubim were lifted up
From the earth; (See Gill on Ezekiel 1:19); this [is] the living creature that I saw by the river Chebar :
a river in Chaldea, where the prophet was when he had the vision of the living creatures recorded in the "first" chapter; and hence it is out of doubt that the living creatures and the cherubim are the same.
