Ezekiel 10:1

Then I looked, and, behold
After the vision of the destruction of the greater part of the inhabitants of Jerusalem by the six men with slaughter weapons, and of the preservation of a few by the man clothed with linen; another vision is seen by the prophet, in some things like to that he saw, of which there is an account in the first chapter; though in some circumstances different, and exhibited with a different view; partly to represent the destruction of Jerusalem by fire, and partly the Lord's removal from it, before or at that time: in the firmament that was above the head of the cherubim;
the same with the living creatures, ( Ezekiel 1:22 Ezekiel 1:26 ) ; where the firmament or expanse of heaven is said to be over their heads, as here; (See Gill on Ezekiel 1:22): there appeared over them as it were a sapphire stone, as the appearance
of the likeness of a throne; (See Gill on Ezekiel 1:26).
