1 Corinthians 7:15-16

New American Standard Bible

¹⁵ Yet if the unbelieving one is leaving, ^[a]let him leave; the brother or the sister is not under bondage in such cases, but God has called ^[b]us ^(A)in peace. ¹⁶ For how do you know, wife, whether you will ^(B)save your husband? Or how do you know, husband, whether you will save your wife?
