There are two references to the 144,000 in the Book of Revelations. These "chosen" are the 12 legions mentioned in the Gospel of Mark, 12 000 per legion, 12 legions, 144,000. The references in Revelation are at the beginning of chapters 7 and 14. 7 x 2 = 14. 72 x 2 = 144. Or, 2/5s the circumference of a circle (72, 144, 216, 288, 360/0). This 3:2 ratio is known as the Perfect Fifth:
"In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. The perfect fifth may be derived from the harmonic series as the interval between the second and third harmonics"
Rev 7:2-4 He called out in a loud voice to the four angels who had been given power to harm the land and the sea: “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.” Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel.
Rev 14:1-3 Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads. And I heard a sound from heaven like the roar of rushing waters and like a loud peal of thunder. The sound I heard was like that of harpists playing their harps. And they sang a new song before the throne and before the four living creatures and the elders. No one could learn the song except the 144,000 who had been redeemed from the earth.
So as you can see, there's a "call back" to both the 144,000 AND the 4 angels. 7/14(7x2)/144(72x2). This is not an accident or coincidence.
I say on an encoded level its about perfect fifths and harmonics, and IN THE TEXT it's saying " The sound I heard was like that of harpists playing their harps. And they sang a new song before the throne and before the four living creatures and the elders "
