Vayyiqra (Leviticus) 23:4
"These are the appointed feasts of YHWH, even holy convocations, which you shall proclaim in their appointed season."
It is a popular teaching today to say that Mashiach Yeshua fulfilled the spring feasts with His first coming and that He will fulfill the fall feasts with His second coming. However, as appealing as this sounds to the flesh, this does not really fit with what one finds in Scripture. Such a position is woefully inadequate. For example, it is often pointed out that the Blood of Mashiach atones for our sins; in fact, Scripture says as much. We find this portrayed in the feast of Yom HaKippurim, a fall feast. Furthermore, while He died on Aviv 14, which is the day of the killing of the Pesach lamb, and the striking of the doorposts and the lintel with the blood of the lamb, to date, the death angel has not passed over the world as foretold in the first Pesach. Nevertheless, we find this passage in the book of Revelation.
Ma'aseh (Revelation) 14:18-19
18 And another angel came out from the altar, he that has power over fire; and he called with a great voice to him that had the sharp sickle, saying, "Send forth your sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe."
19 And the angel cast his sickle into the earth, and gathered the vintage of the earth, and cast it into the winepress, the great winepress, of the wrath of Elohim.
Here we find an exact description of the death angel passing over the entire earth. This was foreshadowed in the first Pesach. What Mashiach Yeshua did was to fulfill the first part of Pesach with His first coming; He will fulfill the rest of Pesach with His second coming. In fact, what He did with His first coming was to begin fulfilling each and every feast, and He will complete the fulfillment of each and every feast with His second coming.
The following chart depicts His first and second comings along with their respective fulfillments. This is an overview to give one a more complete picture of this idea found in Scripture.
