Numbers 9:13-14 ▼

13 “But those who neglect to celebrate the Passover at the regular time, even though they are ceremonially clean and not away on a trip, will be cut off from the community of Israel. If they fail to present the LORD’s offering at the proper time, they will suffer the consequences of their guilt.

14 And if foreigners living among you want to celebrate the Passover to the LORD, they must follow these same decrees and regulations. The same laws apply both to native-born Israelites and to the foreigners living among you.”
