On Jesus and Paul on divorce, I recommend http://www.instone-brewer.com. If you do not know the 1st century context, it is almost certain the relevant verses will be misunderstood.  To answer your specific point/question, Jesus is responding to one question about the meaning of Deu 24:1 when tended toward license and Paul is responding to an entirely different question from some at Corinth that tended to legalism.  They are each answering different questions.  Think of a rower in a river, if you get too close to one shore, someone might shout, “Go left!” and if you get to close to the other shore another might shout, “Go right!”.  These 2 commands just SEEM to contradict each other, but do not when the full context is understood.
