In the Torah we are told to count forty nine days – seven weeks of days – from the day following Passover until Shavuot (i.e., Weeks or “Pentecost”). This period of time is called Sefirat HaOmer (ספירות העומר), or the “counting the [barley] sheaves” (see Lev. 23:15-16; Deut. 16:9). In somewhat abstract terms, it’s as if there is a dotted line pointing directly from Passover to Shavuot – a “Jubilee” of days – representing the climax of Passover itself. The early sages identified this climax as the revelation of the Torah at Sinai — which indeed did happen exactly 49 days after the Passover in Egypt — but the New Testament identifies it as the outpouring of the Holy Spirit (רוח הקודש) that ratified the reality of the New Covenant of God at Zion. In other words, the redemption process that began at Passover was therefore completed at Shavuot, and that “completion” was the revelation of God’s love and deliverance for the entire world. And though the Jewish sages did not fathom the use of the otherwise forbidden leaven in the offering (see Lev. 2:11), prophetically the waving of two loaves during Shavuot pictured the “one new man” (composed of both Jew and Gentile) standing before the altar of the LORD (Eph. 2:14).
The countdown to Shavuot therefore goes beyond the giving of Torah at Sinai and points to the greater revelation of Zion. Shavuot is the fulfillment of the promise of the Holy Spirit’s advent to those who are trusting in Messiah (Acts 2:1-4). “Counting the Omer,” then, is about receiving the Holy Spirit to experience and know the resurrected LORD of Glory. You can “count” on that, chaverim!
In this connection note again that the climax of the 49 days was not the giving of the law at Sinai (i.e., matan Torah), but rather the revelation of the altar (i.e., the“Tabernacle”) and its subsequent fulfillment in the sacrificial death of Yeshua as our Lamb of God. Moreover, it was during this time that Yeshua made His post-resurrection appearances to His disciples and indeed ascended to heaven during this period… Of particular importance is 1) the beginning of the count of the omer since it signified the waving of the firstfruits and therefore the resurrection of Yeshua (1 Cor. 15:20); 2) the 40th day of the Omer (Mem B’Omer), when Yeshua ascended back to heaven, and 3) the climactic 49th day of the Omer (Shavuot) when the Holy Spirit was given to the disciples in fulfillment of the promise of Yeshua that we would not be left comfortless (Acts 2:1-4). Shavuot, then, marks the time of “Jubilee” of the Spirit, when are clothed with power to serve the LORD without fear…
Note: Some people get a bit “OCD” about the 49 day countdown, making it into a religious ritual with “kabbalistic” overtones, but the Torah simply says to count down the days until Shavuot, or Pentecost, since this has major implications regarding the advent of Messiah and the promise of the New Covenant….
