Isaiah 6:2-4 Seraphs are standing above it: six wings hath each one; with two each covereth its face, and with two each covereth its feet, and with two each flieth.

YLT⁽ⁱ⁾ ² Seraphs are standing above it: six wings hath each one; with two each covereth its face, and with two each covereth its feet, and with two each flieth. ³ And this one hath called unto that, and hath said: `Holy, Holy, Holy, is Jehovah of Hosts, The fulness of all the earth is His glory.' ⁴ And the posts of the thresholds are moved by the voice of him who is calling, and the house is full of smoke.
