'Coals' in the Bible

So each man took his censer, put fire coals inside of it, placed incense in it, and then stood at the entrance to the Tent of Meeting, accompanied by Moses and Aaron.

"Tell Aaron's son Eleazar the priest to take out the censers out of the flames and scatter the coals far away, since they are holy.

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!"

So Aaron did as Moses commanded and ran into the middle of the assembly, where the plague was just beginning among the people. So he placed incense on the coals and made atonement for the people.
