Isaiah 6:2-3

Douay-Rheims 1899 American Edition

² Upon it stood the seraphims: the one had six wings, and the other had six wings: with two they covered his face, and with two they covered his feet, and with two they hew.

³ And they cried one to another, and said: Holy, holy, holy, the Lord God of hosts, all the earth is full of his glory.
