The fourth of the seven Feasts of Israel, is known as the Feast of Wave Loaves, the Feast of Weeks, and the Feast of Pentecost. The latter two names refer to the fifty days span from Passover unto Pentecost. The name, the Feast of Wave Loaves, has to do with the offering used. The Priest would bake two loaves of bread with leaven (always a picture of sin). As Christians, we recognize this feast as representing the founding of the Church, which consists of both imperfect Jewish and Gentile believers in Christ (Lev. 23:15-17; Acts 2:1-42).
There remain three Feasts of the Lord, each picturing an aspect of Christ's Second Coming. Because these have yet to be fulfilled, we do not have the luxury of interpreting them after the fact. Therefore, the following is my somewhat educated guess as to how they will be fulfilled.
The Feast of Trumpets: "And the LORD spake unto Moses, saying, Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation. Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the LORD" (Lev. 23:23-25; see Num. 29:1-6 for a description of the offering made by fire). I believe the reason the feast refers to trumpets in the plural, is that two events, closely related to one another in time, each involve the sounding of a trumpet: the Rapture of the Church to meet the Lord in the air (Jn. 1:1-3; 1 Cor. 15:51-52; 1 Thes. 4:13-18); and the gathering of Israel, first by the peace treaty with the Antichrist (Dan. 9:27; Mt. 24:3-15; Rev. 6 - 12); and at the Second Coming of Christ following the seven-year Tribulation (Mt. 24:29-31).
I believe the last two feasts, the Feast of Atonement, and the Feast of Tabernacles, represent Christ's Second Coming. He is the Atonement for sin (Rom. 5:11), and He will dwell (tabernacle) with His people for 1000 years in His Millennial Kingdom (Rev. 20:1-6).
For your sake, I hope the next Trump of God you hear, is that of His Rapture call!
