Day of Atonement
„And יהוה spoke to Mosheh, saying, “On the tenth day of this month seventh month is the Day of Atonement. It shall be a set-apart gathering for you. And you shall afflict your beings, and shall bring an offering made by fire to יהוה.“And you do no work on that same day, for it is the Day of Atonement, to make atonement for you before יהוה your HaElohim.“For any being who is not afflicted on that same day, he shall be cut off from his people. “And any being who does any work on that same day, that being I shall destroy from the midst of his people.“You do no work – Statue forever throughout your generations in all your dwellings.‘It is a Sabbath of rest to you, and you shall afflict your beings. On the ninth day of the month at evening, from evening to evening, you observe your Sabbath.”

Festival of Booths:
and יהוה spoke to Mosheh, saying,“speak to the children of Yisra’ĕl, saying, ‘On the fifteenth day of this seventh month is the Festival of Booths for seven days to יהוה. ‘On the first day is a set-apart gathering, you do no servile work.‘For seven days you bring an offering made by fire to יהוה. On the eighth day there shall be a set-apart gathering for you, and you shall bring an offering made by fire to יהוה. It is a closing festival, you do no servile work.‘These are the appointed times of יהוה that you proclaim as set-apart gatherings, to bring an offering made by fire to יהוה, a burnt offering and a grain offering, a slaughtering and drink offerings, as commanded for every day – besides the Sabbaths of יהוה, and besides your gifts, and besides all your vows, and besides all your voluntary offerings which you give to יהוה. On the fifteenth day (full moon) of the seventh month, when you gather in the fruit of the land, observe the festival of יהוה for seven days. On the first day is a rest, and on the eighth day a rest.‘And you shall take for yourselves on the first day the fruit of good trees, branches of palm trees, twigs of leafy trees, and willows of the stream, and shall rejoice before יהוה your :him for seven days. ‘And you shall observe it as a festival to יהוה for seven days in the year – a law forever in your generations. Observe it in the seventh month. Dwell in booths for seven days; all who are native Yisra’ĕlites dwell in booths,so that your generations know that I made the children of Yisra’ĕl dwell in booths when I brought th em out of the land of Mitsrayim. I am יהוה your HaElohim.’ ”
