Leviticus 1:3

If his offering is a burnt offering from the herd , he shall offer a male without blemish . He shall bring it to the entrance of the tent of meeting , that he may be accepted before the Lord .

“‘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.

If his offering be a burnt sacrifice of the herd, let him offer a male without blemish : he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the Lord.
