IN the Apocalypse the Lamb is brought to our notice in a very striking way. John wept that none was able to open the seals which revealed things which must come to pass. He was told not to weep: "Behold, the Lion of the tribe of Judah, the Root of David, has prevailed to open the book." Thus encouraged John looked as commanded, but it was not a Lion that met his eyes, but "a Lamb as it had been slain." The Lion phase is based upon the Lamb phase; the foundation of all future power and glory being laid in the death of the Lamb. The metaphor wears so thin that the Lamb becomes a title of the Lord Jesus in several places of the Apocalypse (14:4; 15:3; 17:14; 19:7-9; 21:9, 22, 23)

These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb. (Rev. 14:4).

And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints. (Rev. 15:3).

These shall make war with the Lamb, and the Lamb shall overcome them: for he is Lord of lords, and King of kings: and they that are with him are called, and chosen, and faithful. (Rev. 17:14).

Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready. And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints. And he saith unto me, Write, Blessed are they which are called unto the marriage supper of the Lamb. And he saith unto me, These are the true sayings of God. (Rev. 19:7-9).

And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife. (Rev. 21:9).

And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it. And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof. (Rev. 21:22-23).
