Day of Atonement (to cover, purge, reconcile, getting two things to be compatible with one another - in this case: flesh and spirit)
And the Lord spoke* to Moses, saying: “Also the tenth day of this seventh month shall be
the Day of Atonement. It shall be a holy convocation for you; you shall
afflict your souls, and offer an offering made by fire to the Lord. And you shall do no work on that same day, for it is the Day of Atonement, to make atonement for you before the Lord your God
For any person who is not afflicted in soul on that same day shall be cut off from his people. And any person who does any work on that same day, that person I will destroy from among his people. You shall do no manner of work; it shall be a statute forever throughout your generations in all your dwellings. (has forever past?)
It shall be to you a sabbath of solemn rest, and you shall afflict your souls; on the ninth day of the month at evening, from evening to evening, you shall celebrate your sabbath.” (a High Day of rest, not the weekly Sabbath) ~Leviticus 23:26-32
*That is the pattern under the Old/First Covenant. Under the New/Second Covenant we are to offer our body as a living sacrifice made by the fire of not conforming to the world system.
The Hebrew word for affict (yāḡâ means to grieve) has a spiritual meaning and does not mean to fast (ṣûm means to abstain from food - a Jewish tradition on the Day of Atonement). Here is the root meaning: to answer, respond, speak, shout, to testify as a witness. Rather than fast, God is telling us to be witnesses and to remember the grief suffered by Yahshua/Jesus on the cross in our stead. The Day of Atonement also connotes our grieving to be reconciled to God by the atoning sacrifice of Messiah. ~ Romans 5:10
Indeed, God has given us the ministry of reconciliation. ~ 2 Corinthians 5:18. First, reconcile ourself, then reconcile our family, reconcile our community, and reconcile our nation to The Way.
I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God. ~ Romans 12:1-2
