Apocalypse 13:18. Here is wisdom. He that hath understanding, let him count the number of the beast. For it is the number of a man: and the number of him is six hundred sixty-six.
Six hundred sixty-six... The numeral letters of his name shall make up this number.
Immediately after that chapter, the very same verse is about 144.000:
Apocalypse Chapter 14
14:1. And I beheld: and lo a Lamb stood upon mount Sion, and with him an hundred forty-four thousand, having his name and the name of his Father written on their foreheads.
14:2. And I heard a voice from heaven, as the noise of many waters and as the voice of great thunder. And the voice which I heard was as the voice of harpers, harping on their harps.
14:3. And they sung as it were a new canticle, before the throne and before the four living creatures and the ancients: and no man could say the canticle, but those hundred forty-four thousand who were purchased from the earth.
14:4. These are they who were not defiled with women: for they are virgins. These follow the Lamb whithersoever he goeth. These were purchased from among men, the firstfruits to God and to the Lamb.
14:5. And in their mouth there was found no lie: for they are without spot before the throne of God.
Quoting: Anonymous Coward 12871281 Isaiah 6:1-6:
1 In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a
throne; and the train of his robe filled the temple.
2 Above him were seraphim,
each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying.
3 And they were calling to one another:
“Holy, holy, holy is the LORD Almighty;
the whole earth is full of his glory.” 4 At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.
5 “Woe to me!” I cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty.”
6 Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar.
