Give these instructions to the whole community of Israel: On the tenth day of this month each man must choose either a lamb or a young goat for his household.

Then, on the evening of the fourteenth day of the month, the whole community of Israel will kill the animals.

But if any of you are ritually clean and not away on a journey and do not observe the Passover, you shall no longer be considered my people, because you did not present the offering to me at the appointed time. You must suffer the consequences of your sin.
