'Immorality' in the Bible

But I say to you, any man who divorces his wife, except for sexual immorality, causes her to commit adultery, and whoever marries a divorced woman commits adultery."

It is out of the heart that evil thoughts come, as well as murder, adultery, sexual immorality, stealing, false testimony, and slander.

I tell you that whoever divorces his wife, except for sexual immorality, and marries another woman commits adultery."
