(Odkazy: Apocalypse Explained 13, 773; Revelation 13:11)

275. The four living creatures and the twenty-four elders fell down before the Lamb. This symbolizes a humility and out of humility worship of the Lord on the part of the higher heavens.

There follows now a glorification of the Lord on account of the foregoing, for as we said in no. 263 above, if the Lord had not executed a last judgment and thereby put back into order everything in heaven and on earth, all would have perished.

The glorification of the Lord that follows now comes first from the higher heavens, then from the lower heavens, and finally from the lowest heavens - from the higher heavens in verses 8-10, from the lower heavens in verses 11, 12, and from the lowest heavens in verse 13. And lastly there is a confirmation and worship by the higher heavens in verse 14.

The higher heavens, then, are symbolically meant by the four living creatures and twenty-four elders, for cherubim in the midst of the throne - which the four living creatures are - symbolize the Lord in relation to the Word, while the cherubim around the throne, or the four living creatures, symbolize heaven in relation to the Word. For we are told that "in the midst of the throne, and around the throne," John saw "four living creatures full of eyes in front and in back" (chapter 4, 4:6). That is because the heavens are heavens in consequence of their reception of Divine truth from the Lord through the Word.

The twenty-four elders, too, symbolize angels in the higher heavens, since these elders were the closest ones around the throne (chapter 4, 4:4).

To fall down before the Lamb clearly means humility, and out of humility, worship.
