'Burnt offerings' in the Bible

as Moses the servant of Jehovah commanded the children of Israel, as it is written in the book of the law of Moses, an altar of unhewn stones, upon which no man had lifted up any iron: and they offered thereon burnt-offerings unto Jehovah, and sacrificed peace-offerings.

but it shall be a witness between us and you, and between our generations after us, that we may do the service of 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 time to come, Ye have no portion in Jehovah.
