Zechariah 11:7-11. Three Shepherds And The Revoked Covenant.
Zechariah 11
7 So I pastured the flock marked for slaughter, particularly the oppressed of the flock. Then I took two staffs and called one Favor and the other Union, and I pastured the flock.
8 In one month I got rid of the three shepherds.
The flock detested me, and I grew weary of them 9 and said, "I will not be your shepherd. Let the dying die, and the perishing perish. Let those who are left eat one another's flesh."
10 Then I took my staff called Favor and broke it, revoking the covenant I had made with all the nations.
11 It was revoked on that day, and so the afflicted of the flock who were watching me knew it was the word [Yahshua] of [the Lord / Yahwah.]
The Sanhedrin (Hebrew and Aramaic: סנהדרין; Greek: Συνέδριον, synedrion, "sitting together," hence "assembly" or "council") was an assembly of twenty-three or seventy-one rabbis appointed to sit as a tribunal in every city in the ancient Land of Israel.
The Sadducees were members of a Jewish sect founded in the second century BC, possibly as a political party. They ceased to exist sometime after the first century AD.
The Pharisee were founded in 167 BC, they were a ("separatist") party that emerged largely out of a group of scribes and sages. Their name comes from the Hebrew and Aramaic parush or parushi, which means "one who is separated.
Thus the Three Shepherds: Sanhedrin, Sadducees, and Pharisees.
