Leviticus begins with instructions governing the sacrifices offered by the Israelites at the tabernacle. These offerings formed an important part of Israel's worship and expressed devotion, thanksgiving, reconciliation, and the desire to approach God.
When an Israelite brought a burnt offering from the herd, the animal was required to be a male without blemish. The offering was presented at the entrance to the tabernacle, where the worshiper laid a hand upon the animal before it was sacrificed.
The requirement that the animal be without blemish reflected the sacred character of the offering. God was to receive an animal suitable for sacrifice rather than one that was defective or unfit.
The burnt offering was wholly consumed upon the altar, symbolizing the complete dedication of the offering to God.
