There is a tribe in Zimbabwe that follow many of the Jewish customs like not eating pork, keeping the Sabbath (but not mentioned in this link), and now have been shown to have Hebrew DNA. Of course it is very interesting to me to see that they kept the Sabbath for many centuries, all basically unknown to the outside world.

If they can accept Jesus, and keep the commandments, surely they will be in heaven. It makes me wonder how many “hidden tribes” God has reserved unto himself?
