'Divorces' in the Bible

“It has also been said, ‘Whoever divorces his wife is to give her a certificate of divorce’;

but I say to you that whoever divorces his wife, except on grounds of sexual immorality, causes her to commit adultery; and whoever marries a woman who has been divorced commits adultery.

I say to you, whoever divorces his wife, except for sexual immorality, and marries another woman commits adultery.”
