Leviticus 1:3
If the offering is a burnt offering from the herd, you are to offer a male without defect. You must present it at the entrance to the tent of meeting so that it will be acceptable to the Lord. The burnt offering from the herd requires a male without defect — the best available, without blemish. The location is the entrance to the tent of meeting, the threshold of the sacred space where sacrifice makes approach possible. The purpose is acceptability before the Lord — the offering must meet the standard of what is pleasing to God. 1 Peter 1:19 describes Christ as a lamb without blemish or defect — the unblemished male of the burnt offering is the type of the one spotless sacrifice that the entire Levitical system foreshadows.
