'Burnt offerings' in the Bible

as Moses the servant of Jehovah had commanded the children of Israel, as it is written in the book of the law of Moses, an altar of whole stones, over which iron had not been lifted up. And they offered up burnt-offerings on it to Jehovah, and sacrificed peace-offerings.

but to be a witness between us and you, and between our generations after us, that we might do service to Jehovah before him with our burnt-offerings, and with our sacrifices, and with our peace-offerings; that your children may not say to our children in future, Ye have no portion in Jehovah.
