So, as it is written [Jer. 9:23f], "The person who [wants to] boast, let him boast about the Lord."

Yet if the unbelieving mate separates [from his spouse], let him go. The brother or sister is not obligated [to continue the marriage] under such circumstances. For God has called you [believers] to live in peace.

So, do not let anyone look down on him, but help him on his journey in peace so that he can come to me, for I am expecting him [to come] with the brothers.
