When Jesus had Bible study with the two disciples from Emmaus, He said to them:
“How foolish you are, and how slow to believe all that the prophets have spoken! Did not the Messiah have to suffer these things and then enter his glory?” And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself. (Luke 24:25-27)
So when we study the Law and the Prophets (the Old Testament), we should be looking for Jesus. Sometimes its obvious that the story is about Jesus, sometimes it is not, like in the rather bizarre story that Dr. Bramson examines in this lesson. When snakes bit the Israelites (Numbers 21:4-9) and Moses made that bronze serpent-on-a-pole, how was that about Jesus?
