Revelation 14:1, 13-14

And I saw, and behold, the Lamb standing on the mount Zion, and with him a hundred and forty and four thousand, having his name, and the name of his Father, written on their foreheads.

And I heard a voice from heaven saying, Write, Blessed are the dead who die in the Lord from henceforth: yea, saith the Spirit, that they may rest from their labors; for their works follow with them. And I saw, and behold, a white cloud; and on the cloud I saw one sitting like unto a son of man, having on his head a golden crown, and in his hand a sharp sickle.
