Most Christians who know about the Rapture and look longingly for it, think that the Rapture is prophecied only in the New Testament. They think there is no information about it in the Tanach (the Bible from Genesis to Malachi).
The Feast of Trumpets prefigures the Rapture. The first mention of the Trumpet is in the book of Exodus before God gave the Ten Commandments. It was at Sinai, and the purpose of it was to announce the coming of the Lord in glory on the Mountain of God.
Joshua delivered His people to their promised Land at the sound of a trumpet.
The Feast of Trumpets was instituted in Leviticus 23:42. The Rapture is the event which will fulfill the Feast of Trumpets, just as Jesus’ saving death fulfilled Passover, and the descent of the Holy Spirit in tongues of fire fulfilled Pentecost, the Sinai event when God came down upon the Mount in flames of fire.
We set out below the Feasts of the Lord, and each is linked to a page that gives detailed information about the Feast as it was ordained to be celebrated, the changes that were made when the first Temple was destroyed and the Jews were sent into exile in Babylon, and the further changes that were made after their return to the Land, and the yet further changes that were made after the second Temple was destroyed and the Jews scattered around the world.
Since the Feasts were to be celebrated by gathering to the Temple in Jerusalem, and the Jews were deprived of the Temple and exiled first to Babylon and then into the nations of the world, they were confronted with the need to make changes that would enable annual celebration of the Feasts in every nation, and in the absence of a Temple to even face toward.
Also, for each Feast, we will set out its prophetic signifance, and whether fulfilled or to be fulfilled, and the broad outlines of the expected fulfillment.
