In the first month of the second year after leaving Egypt, the Lord tells Moses that the Israelites are to keep the Passover at its appointed time, at twilight on the fourteenth day. They keep it in the wilderness of Sinai, according to all that the Lord had commanded.
Some men, unclean from having touched a dead body, cannot keep it on that day. They come before Moses and Aaron and ask why they should be left without the Lord's offering. Moses consults the Lord, and the answer establishes a Passover in the second month, at twilight on the fourteenth day, for those who are unclean or on a distant journey. It is to be eaten with unleavened bread and bitter herbs, leaving none until morning and breaking no bone. But anyone who is clean and not on a journey and still fails to keep it will be cut off from his people. The foreigner who lives among them may also keep it, under the same rule.
The chapter ends with the cloud. On the day the tabernacle was set up, the cloud covered it, and at night it looked like fire. When the cloud lifted, the Israelites set out; where it settled, they camped. Whether the cloud stayed two days, a month or a year, the people stayed. Everything was done at the Lord's command.
