The Biblical feast of Shavuot begins Thursday evening and ends Saturday evening. God gave His commandments twice during this feast: He wrote them on stone tablets in the Old Testament, and on the hearts of men in the New Testament. The response was mixed. Three thousand Israelites died at Mount Sinai after worshipping a golden calf. Three thousand were saved in Jerusalem after receiving the gospel shared by Yeshua’s disciples, filled with the Holy Spirit for the first time.
Shavuot (Pentecost in Greek) occurs 50 days after Passover. It is the last of the spring Biblical feasts, which Yeshua fulfilled with His first coming. He will fulfill the fall feasts with His second coming.
