'Sojourning' in the Bible
When a stranger sojourning with you wishes to 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. But no uncircumcised person shall eat of it.
You shall have one law for him who sins unknowingly or unintentionally, whether he is native born among the Israelites or a stranger who is sojourning among them.
These cities were for all the Israelites and the stranger sojourning among them, that whoever killed a person unintentionally might flee there and not be slain by the avenger of blood until he had been tried before the congregation.
