a live, burning coal: a glowing ember, still hot, as opposed to cold spent charcoal
This word names one specific thing: a coal that is still burning, a glowing ember rather than cold, spent fuel. That single vivid image does a great deal of work across the Hebrew Bible, because a live coal has three qualities at once. It can be picked up and carried, it acts decisively the instant it touches whatever it meets, and it can be put out.
Those three qualities shape how the word is used:
- Because a coal is portable, it becomes the piece of altar-fire the high priest carries into the most sacred place (Leviticus 16:12), and the everyday fuel a craftsman bakes his bread over (Isaiah 44:19).
- Because a coal is decisive on contact, it becomes the burning ammunition of God's fiery presence in the storm-poems (Psalm 18) and the fire hurled down on enemies (Psalm 140:10).
- Because a coal can be extinguished, it becomes a picture of a fragile human life: the wise woman of Tekoa calls her last surviving son "my coal that is left" (2 Samuel 14:7), the one ember that could still rekindle a family.
Hebrew keeps a separate word for the cold, unlit fuel, charcoal (פֶּחָם), and Proverbs 26:21 lines the two up on purpose. That contrast is the key to the word: it is never dead fuel but always fire you could hold in your hand.
Nuances
Whether the man clothed in linen scatters the coals over Jerusalem as an act of destruction or sprinkles them as a priestly cleansing.
- majorityHe scatters the burning coals over the city in judgment; the same fire that once sanctified the altar is now turned to consume Jerusalem.; W. Zimmerli, Ezekiel 1 (Hermeneia; Fortress, 1979), 226, 231-34; M. Greenberg, Ezekiel 1-20 (AB 22; Doubleday, 1983), 179-81; D. I. Block, Ezekiel 1-24 (NICOT; Eerdmans, 1997), 313-34

What the burning coals heaped on an enemy's head are meant to accomplish.
