'Burning Coals' in the Bible

“Say to Eleazar, the son of Aaron the priest, that he shall take up the censers out of the midst of the blaze, for they are holy; and you scatter the burning coals abroad.

Then Moses said to Aaron, "Take the censer, put burning coals from the altar in it, place incense on it, and go quickly into the assembly and make atonement for them, for wrath has gone out from the Lord -- the plague has begun!"
