June 19th, 2016: Not just one day called Shavuot (Pentecost), but for FOUR months firstfruits brought to the Father's house in 2Chronicles 31

5 And as soon as the commandment came abroad, the children of Israel brought in abundance the FIRSTFRUITS of corn, wine, and oil, and honey, and of all the increase of the field; and the TITHE of all things brought they in abundantly. 

6 And concerning the children of Israel and Judah, that dwelt in the cities of Judah, they also brought in the TITHE of oxen and sheep, and the TITHE of holy things which were consecrated unto the Lord their God, and laid them by heaps. 

7 In the third month they began to lay the foundation of the heaps, and finished them in the seventh month. 

8 And when Hezekiah and the princes came and saw the heaps, they blessed the Lord, and his people Israel. 

9 Then Hezekiah questioned with the priests and the Levites concerning the heaps. 

10 And Azariah the chief priest of the house of Zadok answered him, and said, Since the people began to bring the offerings INTO THE HOUSE OF THE LORD, we have had enough to eat, and have left plenty: for the Lord hath blessed his people; and that which is left is this great store.

“Say not ye, There are yet FOUR months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest.” John 4:35
