Numbers 9:8 WEB

⁶  There were certain men, who were unclean because of the dead body of a man, so that they could not keep the Passover on that day, and they came before Moses and before Aaron on that day.

⁷  Those men said to him, 'We are unclean because of the dead body of a man. Why are we kept back, that we may not offer the offering of Yahweh in its appointed season among the children of Israel?'

⁸  Moses answered them, 'Wait, that I may hear what Yahweh will command concerning you.'

⁹  Yahweh spoke to Moses, saying,

¹⁰  'Say to the children of Israel, 'If any man of you or of your generations is unclean by reason of a dead body, or is on a journey far away, he shall still keep the Passover to Yahweh.
