Numbers 9:4-12

4So Moses told the children of Israel that they should keep the Passover.

5And 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.

6Now 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.

7And those men said to him, “We became defiled by a human corpse. Why are we kept from presenting the offering of the Lord at its appointed time among the children of Israel?”

8And Moses said to them, “Stand still, that I may hear what the Lord will command concerning you.”

9Then the Lord spoke to Moses, saying,

10“Speak to the children of Israel, saying: ‘If anyone of you or your posterity is unclean because of a corpse, or is far away on a journey, he may still keep the Lord’s Passover.

11On the fourteenth day of the second month, at twilight, they may keep it. They shall eat it with unleavened bread and bitter herbs.

12They shall leave none of it until morning, nor break one of its bones. According to all the ordinances of the Passover they shall keep it.
