Leviticus 23:26 Yahweh spoke to Moses, saying, 27 “However on the tenth day of this seventh month is the day of atonement. It shall be a holy convocation to you. You shall afflict yourselves and you shall offer an offering made by fire to Yahweh. 28 You shall do no kind of work in that same day, for it is a day of atonement, to make atonement for you before Yahweh your God. 29 For whoever it is who shall not deny himself in that same day shall be cut off from his people. 30 Whoever does any kind of work in that same day, I will destroy that person from among his people. 31 You shall do no kind of work: it is a statute forever throughout your generations in all your dwellings. 32 It shall be a Sabbath of solemn rest for you, and you shall deny yourselves. In the ninth day of the month at evening, from evening to evening, you shall keep your Sabbath.”
On the once yearly solemn day of atonement, the Old Covenant community was given two pictures of the New Covenant atoning sacrifice of the Promised Messiah, Jesus Christ.
First, the people were ransomed from their sins by the blood of the sacrifice.
Second, the scapegoat was driven away into the wilderness to demonstrate that once atoned for, God remembers our sins no more.
While we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! Not only is this so, but we also boast in God through our Lord Jesus Christ, through whom we have now received atonement. Romans 5:10-11
To satisfy justice, Christ, the Lamb of God, standing in our place, gave up his life outside of the city gates to save his people from the wrath that their sins deserved.
