Numbers 9:9 bbe — And the Lord said to Moses,

And there were certain men who were unclean because of a dead body, so that they were not able to keep the Passover on that day; and they came before Moses and before Aaron on that day:

And these men said to him, We have been made unclean by the dead body of a man; why may we not make the offering of the Lord at the regular time among the children of Israel?

And Moses said to them, Do nothing till the Lord gives me directions about you.

Say to the children of Israel, If any one of you or of your families is unclean because of a dead body, or is on a journey far away, still he is to keep the Passover to the Lord:

In the second month, on the fourteenth day, in the evening, they are to keep it, taking it with unleavened bread and bitter-tasting plants;

Nothing of it is to be kept till the morning, and no bone of it is to be broken: they are to keep it by the rules of the Passover.
