The man (not men) being quoted here is Jeremiah himself. See here in Jeremiah 1:18-19
Quote
For, behold, I have made you this day a fortified city, and an iron pillar, and brazen walls, against the whole land, against the kings of Judah, against the princes of it, against the priests of it, and against the people of the land. They shall fight against you; but they shall not prevail against you: for I am with you, says Yahweh, to deliver you.

And I found this using Sword Searcher.


Peter

If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself. Augustine of Hippo
