Yeshua gives us a major hint in the gospels. When He sent out the 12 (a very Jewish number) disciples prior to feeding the 5000, He sent them to a Jewish crowd. There was no need to give them any dietary warnings - they were kosher. Then in Luke 10, we see Him sending out 70 (number of completeness) to a very Gentile area, prior to feeding the 4000. What did He tell them? Eat such things as are set before you. There was a good chance that some of these Gentiles were going to give them pork BBQ.
