Ezekiel 1:22

22. The firmament Literally, And there was the likeness of a firmament, etc. This is a new feature. It seems to rest just above the pavement made by the outstretched wings of the cherubim. It is always elsewhere used in Scripture for the heavens. It is here the platform of Jehovah’s throne. This is the “paved work of a sapphire stone, and as it were the body of heaven in clearness,” which Moses saw under Jehovah’s feet (Exodus 24:10), and which in St. John’s vision became, as it were, “a sea of glass like unto crystal” (Revelation 4:6). If this crystal firmament seemed ablaze, as if “mingled with fire” (Revelation 15:2), it may explain why it seemed to the onlooker “terrible.”
