Arcana Coelestia # 10034
10034. And shalt burn them on the altar. That this signifies from the Lord’s Divine love, is evident from the signification of “burning,” as being the kindling of the Divine love; and from the representation of the altar, as being a representative of the Lord in respect to the Divine good of love (see n. 9388, 9389, 9714). That “to burn” denotes the kindling of the Divine love, is because the Divine love was signified by the fire upon the altar (n. 6832).
Ezekiel 1:26-27
26
Above the expanse that was over their heads was the likeness of a throne, as the appearance of a sapphire stone; and on the likeness of the throne was a likeness as the appearance of a man on it above.
27
I saw as it were glowing metal, as the appearance of fire within it all around, from the appearance of his waist and upward; and from the appearance of his waist and downward I saw as it were the appearance of fire, and there was brightness around him.
