The Gentiles are grafted into Israels covenant. Israel Must atone once a year forever as commanded. Once you as a Gentile are grafted in to Israel or the Olive Tree, you become part of that tree. You must do what the tree does. You must embrace its roots.

Christ is our perfact sacrafice, he paid for all of our sins, however to be obiedent we can all still treat the Day as a Sabbath and fast and atone (humble ourselves and ask forgivness) for our sins.

Rom 11:11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.

Rom 11:12 Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?

Rom 11:13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:

Rom 11:14 If by any means I may provoke to emulation them which are my flesh, and might save some of them.

Rom 11:15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?

Rom 11:16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.

Rom 11:17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;

Rom 11:18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.

Rom 11:19 Thou wilt say then, The branches were broken off, that I might be graffed in.

Rom 11:20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:

Rom 11:21 For if God spared not the natural branches, take heed lest he also spare not thee.

Rom 11:22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.

Rom 11:23 And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.

Rom 11:24 For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?

Lev 16:29 And this shall be a statute for ever unto you: that in the seventh month, on the tenth day of the month, ye shall afflict your souls, and do no work at all, whether it be one of your own country, or a stranger that sojourneth among you:

Lev 16:30 For on that day shall the priest make an atonement for you, to cleanse you, that ye may be clean from all your sins before the LORD.

Lev 16:31 It shall be a sabbath of rest unto you, and ye shall afflict your souls, by a statute for ever.

Lev 16:32 And the priest, whom he shall anoint, and whom he shall consecrate to minister in the priest's office in his father's stead, shall make the atonement, and shall put on the linen clothes, even the holy garments:

Lev 16:33 And he shall make an atonement for the holy sanctuary, and he shall make an atonement for the tabernacle of the congregation, and for the altar, and he shall make an atonement for the priests, and for all the people of the congregation.

Lev 16:34 And this shall be an everlasting statute unto you, to make an atonement for the children of Israel for all their sins once a year. And he did as the LORD commanded Moses.
