I beheld, and lo a likeness, etc. The vision opens with a theophany like that of Ezekiel 1:1-28.; but here, as there, Ezekiel uses the word which emphasizes the fact that what he had seen was but a "likeness" of the ineffable glory, an image of the Unseen.
(For "amber," see Ezekiel 1:4, Ezekiel 1:27.) In this case we note the absence of the cherubic figures. It is simply the "appearance of tile likeness of the glory of Jehovah," seen now in the glow of fire, without the milder, more hopeful brightness of the rainbow (Ezekiel 1:28).
