In Isaiah's vision of God enthroned in the temple, שְׂרָפִים, "burning ones," stand above the throne. Each has six wings: two cover the face, two cover the feet, and two are for flying. They call out to one another, "Holy, holy, holy is the LORD of Hosts," until the doorposts shake and the house fills with smoke.
These beings share their name with the venomous serpent above them in this entry, and most scholars now connect the two. The leading view is that Isaiah pictures his seraphim on the model of the Egyptian winged cobra, a royal guardian creature that shows up constantly on seals and royal art from this period, especially in Judah. Isaiah reworks the image so the wings no longer guard a king: they cover the creatures themselves, because even they cannot bear to stand exposed before God's holiness.
One of the seraphim flies to Isaiah with a live coal taken from the altar and touches it to his lips, declaring his guilt removed and his sin purified, the moment that commissions him to speak for God. Exactly what these beings looked like, whether serpentine, human-shaped, or something in between, is genuinely disputed among scholars, since the vision itself never fully describes their form beyond the wings, the faces, and the hands that hold the tongs. The temple's other well-known throne guardians, the כְּרוּב cherubim, carry and flank God's presence rather than stand above it and sing, so the Bible keeps the two kinds of being distinct even though later art and imagination often blur them together.
