Numbers 9:13-14

13But if anyone who is ceremonially clean and not on a journey fails to celebrate the Passover, they must be cut off from their people for not presenting the Lord’s offering at the appointed time. They will bear the consequences of their sin.

14“ ‘A foreigner residing among you is also to celebrate the Lord’s Passover in accordance with its rules and regulations. You must have the same regulations for both the foreigner and the native-born.’ ”
