MAT 5:32

32 But [now listen to what] I say to you: [A man] may [divorce his wife] only if she has committed adultery, [and not for any other reason]. If a man divorces his wife [for any other reason, and he has sex with another woman], he makes his wife become one against whom he has committed adultery, [because in God’s estimation she still is his wife]. Also, if a man marries a woman who is divorced {whose husband has divorced her}, [God considers] him [guilty of] committing adultery.”
