The sons of Aaron the [high] priest shall put fire on the altar [of burnt offering] and arrange wood on the fire.

Then he shall tear it open by its wings, but shall not sever it. And the priest shall offer it up in smoke on the altar, on the wood that is on the fire. It is a burnt offering, an offering by fire, a sweet and soothing aroma to the Lord.

Aaron’s sons shall offer it up in smoke on the altar [placing it] on the burnt offering which is on the wood that is on the fire. It is an offering by fire, a sweet and soothing aroma to the Lord.

Now Nadab and Abihu, the sons of Aaron, took their respective [ceremonial] censers, put fire in them, placed incense on it and offered strange (unauthorized, unacceptable) fire before the Lord, [an act] which He had not commanded them to do.

You shall not give any of your children to offer them [by fire as a sacrifice] to Molech [the god of the Ammonites], nor shall you profane the name of your God [by honoring idols as gods]. I am the Lord.

For seven days you shall present an offering by fire to the Lord. On the eighth day you shall have a holy convocation and present an offering by fire to the Lord. It is a festive assembly; you shall not do any laborious work [on that day].
