Exodus 12:48
If a foreigner resides with you and wants to celebrate the LORD’s Passover, all the males in the household must be circumcised; then he may come near to celebrate it, and he shall be like a native of the land. But no uncircumcised man may eat of it.
Isaiah 56:3–7
Let no foreigner who has joined himself to the LORD say, “The LORD will utterly exclude me from His people.” And let the eunuch not say, “I am but a dry tree.” / For this is what the LORD says: “To the eunuchs who keep My Sabbaths, who choose what pleases Me and hold fast to My covenant— / I will give them, in My house and within My walls, a memorial and a name better than that of sons and daughters. I will give them an everlasting name that will not be cut off.
