6. There were men who were ritually unclean [because of contact with] a dead person, and therefore could not make the Passover sacrifice on that day. So they approached Moses and Aaron on that day.
7. Those men said to him, "We are ritually unclean [because of contact] with a dead person; [but] why should we be excluded so as not to bring the offering of the Lord in its appointed time, with all the children of Israel?
8. Moses said to them, "Wait, and I will hear what the Lord instructs concerning you."
9. The Lord spoke to Moses saying:
10. Speak to the children of Israel saying, Any person who becomes unclean from [contact with] the dead, or is on a distant journey, whether among you or in future generations, he shall make a Passover sacrifice for the Lord.
What is interesting here is that either the Lord became a little more forgiving, or realized how important Passover is. Is this the same Lord that struck Aaron's sons dead for a minor infraction? Or is the Lord a reflection of the maturity of the people. Though, thinking about it, did this part occur before or after the death of Aaron's sons.
