Numbers 9:6-8

New International Version - UK

⁶ But some of them could not celebrate the Passover on that day because they were ceremonially unclean on account of a dead body. So they came to Moses and Aaron that same day ⁷ and said to Moses, ‘We have become unclean because of a dead body, but why should we be kept from presenting the Lord’s offering with the other Israelites at the appointed time?’

⁸ Moses answered them, ‘Wait until I find out what the Lord commands concerning you.’
