I have Kev...You have to remember the context in which he was asked. The Pharisees were trying to test Jesus and asked him if it was ok to D for any reason at all...Which gets into Matthew 19:9.
When he left out the "exception clause" in Mark 10:2 it was the way the question was noted by Mark, Mark left out the for any reason at all part.
Another way of expressing the framework of these words, is that Jesus was reminding them, that without a “just-cause” for divorcing, it is (and was) not lawful (moral) to divorce and remarry without committing sin (Remember this is the same account as Matthew records).
