“Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’
But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne;Matthew 5:34 NIV
But I tell you that anyone who divorces his wife, except for sexual immorality, makes her the victim of adultery, and anyone who marries a divorced woman commits adultery.Matthew 5:32 NIV
