Bible: Isaiah 6:2-3

6:2 Seraphs 1  stood over him; each one had six wings. With two wings they covered their faces, with two they covered their feet, 2  and they used the remaining two to fly. 6:3 They called out to one another, “Holy, holy, holy 3  is the Lord who commands armies! 4  His majestic splendor fills the entire earth!”
