The Bible record of the first Passover given in Exodus 12 shows that it was kept on the evening at the beginning of the 14th day of the first month with each family killing their own lamb. But by the time of Jesus most Jews were keeping it one day later with the lambs being killed at the temple by the priests. How did these changes come about and are they biblical? In this the first of a two part Bible study series Mr. Smith begins looking at these changes by covering the history of Passover observance from the time of Moses up to the time of David and Solomon.
