Jeremiah 1:18

For, behold, I have made thee this day a defenced city, and an iron pillar, and brasen walls against the whole land, against the kings of Judah, against the princes thereof, against the priests thereof, and against the people of the land.

For, behold, I have made thee this day a defenced city,.... Or, "as" one; so read the Targum, Septuagint, Syriac, and Arabic versions; which is inexpungible, and cannot be taken:

and an iron pillar; which cannot be removed out of its place:

and brasen walls; which cannot be broken down. All these metaphors show the safety and security of the prophet, being surrounded by the power of God; his constancy, immovableness, and invincibleness in the work of the Lord, having such a spirit of power, fortitude, and of a sound mind, that nothing was able to move and shake him, or to deter him from the execution of his office; and that he should stand inflexible

against the whole land; of Judea, and all the inhabitants of it:

against the kings of Judah; in successive reigns, as Jehoahaz, Jehoiakim, Jehoiachin, or Jechonias, and Zedekiah:

against the princes thereof; who desired he might be put to death,

Jeremiah 38:4:

against the priests thereof; who all of them dealt falsely, and were given to covetousness, Jeremiah 8:10:

and against the people of the land; who were grievously addicted to idolatry, and all manner of wickedness.
