'Burnt Offerings' in the Bible

as Moses the servant of the LORD commanded the children of Israel, as it is written in the book of the law of Moses, "an altar of uncut stones, on which no man has touched with an iron tool." They offered burnt offerings on it to the LORD, and sacrificed peace offerings.

but it will be a witness between us and you, and between our generations after us, that we may perform the service of the LORD before him with our burnt offerings, with our sacrifices, and with our peace offerings;' that your children may not tell our children in time to come, 'You have no portion in the LORD.'
