Shavuot is the feast of weeks. In Christianity, it is called Pentecost because it is the 50th day following counting seven complete weeks after Passover. Yeshua gave the Torah at mount Sinai. The themes of Shavuot are giving the Torah, the wedding betrothal, the first trump, the celebration of the wheat harvest and renewing the covenant in Acts 2 through the outpouring of the Holy Spirit. The church was born at mount Sinai. It was reborn in Acts 2 through the renewing of the covenant from Yeshua dying on the tree that was broken at mount Sinai. The new covenant Shavuot represents a change of heart. Passover is linked to Shavuot through the counting of the omer. The omer was threshed, parched in the fire, tossed in the wind, ground into fine flour and went through 13 sieves. Each of these steps is spiritually associated with the life of a believer in Yeshua as one grows in their faith unto Him. In traditional Judaism, the book of Ruth is read during Shavuot. Ruth represents the non-Jewish believers in Yeshua.
