And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood.
And I looked, and, lo, a Lamb stood on Mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads.Actually it says "and with him an hundred forty and four thousand with harps," which elides the line above with the next one:
And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps.Interesting idea this Spanish monk had about harps. I suppose the word "cithara" had come to mean "stringed instrument," so here we have the 144,000 Righteous Guitarists.
Apocalypse of John I recommend taking a look at it. It's not very long and you will see where a long list of famous Christian tropes came from, like the Four Horsemen and the Seven Seals and the 144,000 Righteous. But do not, repeat, DO NOT try to figure out what it means. For that way lies madness. Just skim and think of it as strange poetry.
