As usual, intojoy; you misfire on the Mystery first revealed to and through the Apostle Paul :chuckle:
The following is not said Mystery.
Exodus 12:48 And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
Isaiah 14:1 For the LORD will have mercy on Jacob, and will yet choose Israel, and set them in their own land: and the strangers shall be joined with them, and they shall cleave to the house of Jacob.
