Isaiah 6:2-4 Expanded Bible (EXB)
2 ·Heavenly creatures of fire [L Seraphim; C the word means “burning ones” and points to purity, power, or judgment] ·stood above [or attended] him [Rev. 4:6–9]. Each creature had six wings: It used two wings to cover its face [C as a shield from God’s awesome glory], two wings to cover its ·feet [or body; C indicating humility; “feet” can be a euphemism for genitals], and two wings for flying. 3 Each creature was calling to the others:
“Holy, holy, holy is the Lord ·All-Powerful [Almighty; of Heaven’s Armies; T of hosts].
4 ·Their calling [The sound/noise from each one’s voice] caused the ·frame around the door [doorposts; threshold foundations] to shake, as the Temple filled with smoke.
