Charles Ellicott Commentary Leviticus 1:5

"And he shall kill the bullock before Jehovah: and Aaron`s sons, the priests, shall present the blood, and sprinkle the blood round about upon the altar that is at the door of the tent of meeting." — Leviticus 1:5 (ASV)

And he shall kill the bullock. — The sacrificer himself slaughtered the victim on the north side of the altar by cutting its throat, while a priest or an assistant held a bowl under the neck to receive the blood.

Before the Lord. — That is, before the door of the tent of meeting . The two phrases constantly interchange in the directions about the sacrifices (Leviticus 3:8; Leviticus 3:12; Leviticus 4:4; Leviticus 4:15; Leviticus 4:24; Leviticus 6:18, and other similar verses).

The priests, Aaron’s sons. — Better, the sons of Aaron, the priests, as the Authorized Version renders this phrase in Numbers 10:8. Besides the passage in Joshua 21:19, this phrase occurs only six times: once in Numbers, where it is properly rendered, and five times in this book, where it is translated three times as “the priests Aaron’s sons” (Leviticus 1:5; Leviticus 1:8; Leviticus 1:11), and twice as “Aaron’s sons the priests” (Leviticus 2:2; Leviticus 3:2). (See Leviticus 21:1.)

And sprinkle. — Better, throw the blood. The priestly functions, which began with catching the blood in the bowl, were now to continue in this instance as well. The priest threw the blood upon the walls of the altar in two portions. He first stepped to the north-eastern corner, and from that corner, diffused the blood on the northern and eastern walls; he then placed himself at the south-western corner, from where he diffused the second portion of the blood on the southern and western walls. The rest of the blood he poured out at the Southern side of the altar, which was furnished with two holes; these holes communicated with a drain which conducted the blood into the Kedron.

By the door of the tabernacle. — Better, at the entrance of the tent of meeting. (See Leviticus 1:3.)
