Charles Ellicott Commentary Leviticus 4:4

"And he shall bring the bullock unto the door of the tent of meeting before Jehovah; and he shall lay his hand upon the head of the bullock, and kill the bullock before Jehovah." — Leviticus 4:4 (ASV)

To the door of the Tabernacle of the Congregation. —Better, to the entrance of the tent of meeting. (See Leviticus 1:3.) The regulations about the bringing of the sin offering up to the sprinkling of the blood are the same as those about the other sacrifices.
