1 Now 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 children of Israel keep the Passover at its appointed time.
3 On the fourteenth day of this month, at twilight, you shall keep it at its appointed time. According to all its rites and ceremonies you shall keep it.”
4 So Moses told the children of Israel that they should keep the Passover.
5 And they kept the Passover on the fourteenth day of the first month, at twilight, in the Wilderness of Sinai; according to all that the Lord commanded Moses, so the children of Israel did.
6 Now there were certain men who were defiled by a human corpse, so that they could not keep the Passover on that day; and they came before Moses and Aaron that day.
