R. Yeivi was a student of the Magid. His father was called R. Leib. He was also a Magid in Ostroh. 

[Note: in the Sefer R. Yeivi it is written that his name is an acronym for Ya’akov Yosef Ben Yehuda].

Once the Magid met R. Leib. He told him¹ to send him his son R. Ya’akov Yosef. R. Leib responded that he is my youngest child and an only son to his mother. Thus, he doesn’t want to let him go.

The Magid said: in the end, he will come to me.

Later R. Yeivi strongly opposed the local rabbis. He preached against them and called them Jeroboam son of Nebat. Therefore, they pursued him and he was forced to flee. At that point, he came to the Magid. Thus, the Magid’s prophecy was fulfilled. 

(By the way, R. Yeivi wrote a book against the locally appointed rabbis. Name?).²
