Roman Mass Propers: Epistle "Apocalypse" Ch. 7 vs. 2-12

In those days, behold, I, John, saw another Angel ascending from the rising of the sun, having the sign of the living God. And he cried with a loud voice to the four Angels, to whom it was given to hurt the earth and the sea, saying, Hurt not the earth nor the sea, nor the trees, till we sign the servants of our God in their foreheads. And I heard the number of them that were signed: a hundred and forty-four thousand were signed out of every tribe of the children of Israel. Of the tribe of Juda were twelve thousand signed: of the tribe of Ruben twelve thousand signed: of the tribe of Gad twelve thousand signed: of the tribe of Aser twelve thousand signed: of the tribe of Nephthali twelve thousand signed: of the tribe of Manasses twelve thousand signed: of the tribe of Simeon twelve thousand signed: of the tribe of Levi twelve thousand signed: of the tribe of Issachar twelve thousand signed: of the tribe of Zabulon twelve thousand signed: of the tribe of Joseph twelve thousand signed: of the tribe of Benjamin twelve thousand signed. After this, I saw a great multitude which no man could number, of all nations, and tribes, and peoples, and tongues, standing before the throne and in sight of the Lamb. And all the Angels stood round about the throne, and the ancients, and the four living creatures; and they fell down before the throne upon their faces, and adored God, saying, Amen. Benediction, and glory, and wisdom, and thanksgiving, honor, and power, strength to our God for ever and ever.  Amen
