'Prophet's' in the Bible

Then they said, "Come, let's make up a plot against Jeremiah. After all, the priest's instruction, the wise man's counsel, and the prophet's message won't be destroyed. So let's verbally attack him. Pay no attention to anything he says!"

Then Jeremiah came from Topheth, where the Lord had sent him to give the prophet's word; and he took his place in the open square of the Lord's house, and said to all the people,

I did not send these prophets, but they went running: I said nothing to them, but they gave out the prophet's word

But as for the prophet who [on the contrary] prophesies of peace, when that prophet’s word comes to pass, [only] then will it be known that the Lord has truly sent him.”

they even sent and took Jeremiah out of the court of the guardhouse and entrusted him to Gedaliah [a prominent citizen], the son of Ahikam [who had once saved Jeremiah’s life], the son of Shaphan, to take him home [with him to Mizpah]. So Jeremiah [was released and] lived among the people.
