Confession of Faith
Chapter 24: Of Marriage and Divorce
Q 1. Marriage is to be between one man and one woman: neither is it lawful for any man to have more than one wife, nor for any woman to have more than one husband, at the same time.1
Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.
and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”

and forgets the covenant of her God; (ESV)
