Mark 10:11

And he saith unto them
The same things as in Mt 5:32, 19:9; (See Gill on Matthew 5:32), (See Gill on Matthew 19:9):

whosoever shall put away his wife, and marry another;
when there is no uncleanness in the case; when his former wile has not injured him by violating the marriage bed:

committeth adultery against her;
to the injury of his lawful wife; or "upon her", or "with her", with the person he marries. The Syriac and Persic versions leave out the phrase, "against her".
