Ex 12.1-14,21-28. And the Lord spoke to Moses in the wilderness of Sinai, in the first month of the second year after they had come out of the land of Egypt, saying, 2“Let the people of Israel keep the passover at its appointed time. 3On the fourteenth day of this month, in the evening, you shall keep it at its appointed time; according to all its statutes and all its ordinances you shall keep it.” 4So Moses told the people of Israel that they should keep the passover. 5And they kept the passover in the first month, on the fourteenth day of the month, in the evening, in the wilderness of Sinai; according to all that the Lord commanded Moses, so the people of Israel did. 6And there were certain men who were unclean through touching the dead body of a man, so that they could not keep the passover on that day; and they came before Moses and Aaron on that day; 7and those men said to him, “We are unclean through touching the dead body of a man; why are we kept from offering the Lord's offering at its appointed time among the people of Israel?” 8And Moses said to them, “Wait, that I may hear what the Lord will command concerning you.”
9The Lord said to Moses, 10“Say to the people of Israel, If any man of you or of your descendants is unclean through touching a dead body, or is afar off on a journey, he shall still keep the passover to the Lord. 11In the second month on the fourteenth day in the evening they shall keep it; they shall eat it with unleavened bread and bitter herbs. 12#Ex 12.46; Jn 19.36. They shall leave none of it until the morning, nor break a bone of it; according to all the statute for the passover they shall keep it. 13But the man who is clean and is not on a journey, yet refrains from keeping the passover, that person shall be cut off from his people, because he did not offer the Lord's offering at its appointed time; that man shall bear his sin. 14And if a stranger sojourns among you, and will keep the passover to the Lord, according to the statute of the passover and according to its ordinance, so shall he do; you shall have one statute, both for the sojourner and for the native.”
Ex 40.36-38. On the day that the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony; and at evening it was over the tabernacle like the appearance of fire until morning. 16So it was continually; the cloud covered it by day,#9.16 Gk Syr Vg: Heb lacks by day and the appearance of fire by night. 17And whenever the cloud was taken up from over the tent, after that the people of Israel set out; and in the place where the cloud settled down, there the people of Israel encamped. 18At the command of the Lord the people of Israel set out, and at the command of the Lord they encamped; as long as the cloud rested over the tabernacle, they remained in camp. 19Even when the cloud continued over the tabernacle many days, the people of Israel kept the charge of the Lord, and did not set out. 20Sometimes the cloud was a few days over the tabernacle, and according to the command of the Lord they remained in camp; then according to the command of the Lord they set out. 21And sometimes the cloud remained from evening until morning; and when the cloud was taken up in the morning, they set out, or if it continued for a day and a night, when the cloud was taken up they set out. 22Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel remained in camp and did not set out; but when it was taken up they set out. 23At the command of the Lord they encamped, and at the command of the Lord they set out; they kept the charge of the Lord, at the command of the Lord by Moses.
