Then Zedekiah warned Jeremiah, "Do not let anyone know about this conversation, or you will die.

Jeremiah 38:23
All your wives and children will be brought out to the Chaldeans. And you yourself will not escape their grasp, for you will be seized by the king of Babylon, and this city will be burned down."

Jeremiah 38:25
If the officials hear that I have spoken with you, and they come and demand of you, 'Tell us what you said to the king and what he said to you; do not hide it from us, or we will kill you,'

Then said Zedekiah to Jeremiah, Let no man know of these words, and you shall not die.
