466. Clothed with a cloud, with a rainbow over his head. This symbolizes His Divinity on the natural plane and His Divinity on the spiritual plane.
As the cloud with which the angel was clothed symbolizes the Lord's Divinity on the natural plane, therefore a cloud is used to symbolize the Word in its natural sense (no. 24), which also originates from Him, and which thus pertains to Him and is Him. A rainbow symbolizes the Lord's Divinity on the spiritual plane, and because this exists above the natural plane, the rainbow was therefore seen over the angel's head.
It must be known that the Lord is present with people in His Divinity on the natural plane, with angels of the spiritual kingdom in His Divinity on the spiritual plane, and with angels of the celestial kingdom in His Divinity on the celestial plane. Still, He Himself is not partitioned, but He appears to each person in accordance with that person's character.
The Lord's Divinity on the spiritual plane is also symbolized by a rainbow in Ezekiel:
Above the expanse (of the cherubim)...was the likeness of a throne..., and (on it)...the appearance of a man... ...and from (the fire of) His loins... as it were... the appearance of a rainbow in a cloud on a rainy day... This was the appearance of... the glory of Jehovah. (Ezekiel 1:26-28).
The throne symbolizes heaven; the man on it, the Lord; the fire of His loins, celestial love; and the rainbow, Divine truth on the spiritual plane, which has to do also with His Divine wisdom.
We read of a rainbow also in Genesis:
I have set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth. And... when I (see it)...in the cloud, I will remember... the eternal covenant... (Genesis 9:12-17)
Nothing else is meant by the rainbow here but Divine truth on the spiritual plane present in the natural one in a person who is being regenerated. For when a person is being regenerated, from being natural he is becoming spiritual. And because he has a conjunction of the Lord with him then, therefore we are told that the bow in the cloud would serve as sign of the covenant, a covenant symbolizing conjunction. Rainbows in the world are clearly not a means of conjunction of the Lord with man.
