Matthew 19:8-9

He said to them, Because of your a hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. b And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.”
Some manuscripts add and whoever marries a divorced woman commits adultery; other manuscripts  except for sexual immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery
