Isaiah 6:2-4

New American Standard Bible

² Seraphim were standing above Him, ^(A)each having six wings: with two each covered his face, and with two each covered his feet, and with two each flew. ³ And one called out to another and said,

⁴ And the ^[b]foundations of the thresholds trembled at the voice of him who called out, while the ^[c](D)temple was filling with smoke.
