Happy Feast of Shavuot (“shaw-voo-oat”), the Feast of Pentecost!
The Feast of Pentecost is one that the Lord commanded us to keep “as a lasting ordinance for generations to come, through all your generations, wherever you live.” (That’s Bible-speak for “always and forever”. 
On this feast we are to give an offering to the Lord, do no regular work, and assemble together with others to honor the Lord.
For believers in Messiah, this feast is one that Messiah and the disciples celebrated. Our Master Yeshua didn’t do away with this feast; the disciples celebrated this feast even after Messiah’s death:
When the day of Shavuot 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.
The disciples were assembled together, as commanded in the Torah, for the feast of Shavuot. God sent his Spirit on them as a witness for the huge crowds in Jerusalem for the Feasts.
In addition to God sending his Spirit on the disciples during Shavuot, Jewish tradition holds it was on Shavuot that the Lord gave the Torah to Moses.
This feast has a rich history of God-intervention and Kingdom-building! And in the future, we will see yet more.
Happy Feast of Shavuot, fine blog readers!
