Numbers 9:6-10

King James Version

⁶ And there were certain men, who were defiled by the dead body of a man, that they could not keep the passover on that day: and they came before Moses and before Aaron on that day:

⁷ And those men said unto him, We are defiled by the dead body of a man: wherefore are we kept back, that we may not offer an offering of the Lord in his appointed season among the children of Israel?

⁸ And Moses said unto them, Stand still, and I will hear what the Lord will command concerning you.

⁹ And the Lord spake unto Moses, saying,

¹⁰ Speak unto the children of Israel, saying, If any man of you or of your posterity shall be unclean by reason of a dead body, or be in a journey afar off, yet he shall keep the passover unto the Lord.
