Numbers 9:5-7

New Living Translation

⁵ in the wilderness of Sinai as twilight fell on the fourteenth day of the month. And they celebrated the festival there, just as the Lord had commanded Moses. ⁶ But some of the men had been ceremonially defiled by touching a dead body, so they could not celebrate the Passover that day. They came to Moses and Aaron that day ⁷ and said, “We have become ceremonially unclean by touching a dead body. But why should we be prevented from presenting the Lord’s offering at the proper time with the rest of the Israelites?”
