Numbers 9:14

And Yahweh said to Moses and Aaron, “This is the statute of the Passover: no foreigner shall eat of it;

“All the congregation of Israel shall celebrate this.

“But if a sojourner sojourns with you and celebrates the Passover to Yahweh, let all his males be circumcised, and then let him come near to celebrate it; and he shall be like a native of the land. But no uncircumcised person may eat of it.

‘There shall be one standard of judgment for you; it shall be for the sojourner as well as the native, for I am Yahweh your God.’”

‘As for the assembly, there shall be one statute for you and for the sojourner who sojourns with you, a perpetual statute throughout your generations; as you are, so shall the sojourner be before Yahweh.
