Parallel
Exodus 12:48
Brenton's English Septuagint · Berean Standard Bible
And if any proselyte shall come to you to keep the passover to the Lord, thou shalt circumcise every male of him, and then shall he approach to sacrifice it, and he shall be even as the original inhabitant of the land; no uncircumcised person shall eat of it.
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.
