Leviticus 16:5

“And he shall take of the congregation of the children of Israel two he-goats for a purification for sin offering, and one ram for a whole burnt offering.”

For the congregation of the children of Israel, the whole people, he was to take two he-goats and a ram. The two he-goats were ‘for a purification for sin offering'. As we shall see shortly the two were seen as one. The ram was for a whole burnt offering.

They were types and shadows of the great He-Goat and Ram, the Lamb of God, Who would offer up Himself once-for-all that He might offer Himself without spot to God, purging our consciences from dead works to serve the living God (Hebrews 9:14) and perfecting for ever those whom He sanctified (Hebrews 10:14).
