Isaiah 6:2-4

Amplified Bible, Classic Edition

² Above Him stood the seraphim; each had six wings: with two [each] covered his [own] face, and with two [each] covered his feet, and with two [each] flew.

³ And one cried to another and said, Holy, holy, holy is the Lord of hosts; the whole earth is full of His glory!

⁴ And the foundations of the thresholds shook at the voice of him who cried, and the house was filled with smoke.
