The Feast of Weeks
Shavuot marks the giving of the Law (Torah) at Mount Sinai. It began as an agricultural feast: 'Celebrate the first fruits of the crops you sow in your field.'
"Count off seven weeks from the time you begin to put the sickle to the standing corn. Then celebrate the Feast of Weeks to the Lord your God by giving a freewill offering in proportion to the blessings the Lord your God has given you." (Leviticus 16:9-10)
However, it was on this day - 50th after the first Passover - that Moses was summoned
to appear before God on Mount Sinai to receive Instruction of the Law. It was while the Jews were celebrating this festival that the first fruits of the spiritual harvest which Yeshua came to gather in occurred:
'When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.'
Pentecost now also represents the fulfilment of God's promise to write Torah on our hearts through the power of the Holy Spirit - Ruach Ha Kodesh: I will put my law in their minds and write it on their hearts.'
