And YHVH 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 YHVH. And you shall do no work on that same day, for it is the Day of Atonement, to make atonement for you before YHVH your Elohim. 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.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.” (Lev 23:26–32)

Yeshua the Messiah said,

“Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled. Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven. For I say to you, that unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven. (Matt 5:17–20)

“If you love Me, keep My commandments.” (John 14:15
