Passover to Pentecost is Ressurrection of Yeshua to the giving of the Ten Commandments on Mt. Sinai. This is called Shavout (Pentecost) and falls on June 10-12, The Feast of Pentecost. The Majority of the Church and all the world are not aware of the significance of this season. We celebrate Shavout because it is the birth of God giving His word and birthing a Nation Israel of Covenant. It also is the time of God birthing the Church, Act 2. It is the time when God gave the Ten Commandments on Mt Sinai. It is the time when God chose Jew and Gentile as His people.
It is the time of the number 3. There were 3 divisions to the word. Torah, The Prophets, and New Testament. Three representing Naomi (Jew), Ruth (Gentile) and Boaz (Kinsmen Redeemer.) This also represent a Wedding. God marries the Gentile at Shavout (Pentecost) and He weds the Jew at Sukot (Tabernacles), thus the One New Man of Ephesians. It is the time of Harvest and Revelation. Ruth is betrothed during this season to Boaz. She marries him in the Fall of the year at Feast of Tabernacles. The Harvest is for the months between late spring early gathering until the fall reaping.
Finally this time is significant because of the judgement of the Fruit Trees. In Israel there is a ceremony of the judging of the Fruit bearing trees. I am reminded that without Holy Spirit I cannot bear fruit. Thus I offer myself as a first fruit unto the Lord. Shalom
