Now Pashhur the priest, the son of Immer, who was chief officer in the house of the Lord, heard Jeremiah prophesying these things. Then Pashhur beat Jeremiah the prophet, and put him in the stocks that were in the upper Benjamin Gate of the house of the Lord.” (Jeremiah 20:1–2, ESV)

What Pashhur the priest should have done was support Jeremiah in whatever way he could in order to get God’s message out to as many people as possible.  Who knew?  Perhaps God would grant repentance to the people if there was a mass change of heart like at Nineveh.

What Passhur the priest actually does is exactly the opposite.  He arrests Jeremiah and has him beaten and put in stocks in order to suppress his message.  A fatal error.  Jeremiah is very clear on what will become of Pashhur for his perfidy:

And you, Pashhur, and all who dwell in your house, shall go into captivity. To Babylon you shall go, and there you shall die, and there you shall be buried, you and all your friends, to whom you have prophesied falsely.”” (Jeremiah 20:6, ESV)

So prophesied.  So done.

The Archaeological Study Bible comments here: “The priest Pashhur had pretended to be a prophet. He probably went into exile in 597 b.c., because shortly after that year (see 29:2) two other men in succession replaced him as chief officer in the temple (see 29:25–26).”

We do not have prophets from God who come and stand in our village and proclaim God’s coming judgment.  However, we do not need prophets from God.

And we have the prophetic word more fully confirmed, to which you will do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts,” (2 Peter 1:19, ESV)

God has spoken in his word.  It remains to us as to whether we will act like Jeremiah and believe that what God has spoken he will in fact do, or like Pashhur suppress what God has spoken and keep doing whatever we want to do.
