'Burning' in the Bible

Having a vessel of gold in it for burning perfumes, and the ark of the agreement, which was covered with gold and which had in it a pot made of gold for the manna, and Aaron's rod which put out buds, and the stones with the writing of the agreement;

For if the blood of goats and oxen, and the dust from the burning of a young cow, being put on the unclean, make the flesh clean:

You have not come to a mountain which may be touched, and is burning with fire, and to a black cloud, and a dark smoke, and a violent wind,

For our God is an all-burning fire.
