Apocalypse Revealed # 644
644. 14:15 And another angel came out of the temple. This symbolizes the angelic heaven.
The symbolic meaning of an angel or angels may be seen in nos. 5, 65, 170, 258, 342, 343, 344, 415, 465 above. Here it is the angelic heaven, because we are told that the angel came out of the temple, and a temple symbolizes heaven in respect to the church (nos. 191, 529, 585). For the church exists in heaven just as much as on earth.
Jeremiah 50:44
44
Behold, [the enemy] shall come up like a lion from the pride of the Jordan against the strong habitation: for I will suddenly make them run away from it; and whoever is chosen, him will I appoint over it: for who is like me? and who will appoint me a time? and who is the shepherd who can stand before me?
