and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs at twilight.
But if anyone who is clean and is not on a journey fails to keep the Passover, that person shall be cut off from his people because he did not bring the Lord’s offering at its appointed time; that man shall bear his sin.
Tell all the congregation of Israel that on the tenth day of this month every man shall take a lamb according to their fathers’ houses, a lamb for a household.
