Jeremiah 21:4

4 'Here is what the Lord, the God of Israel, says: You have weapons of war in your hands to defend yourselves against the king of Babylon and the Babylonians, who are all around the city wall. But I will make those weapons useless. Soon I will bring them into the center of this city.

Jeremiah 21:4 Meaning and Commentary

Jeremiah 21:4

Thus saith the Lord God of Israel
Who had been, still was, and would be, Israel's God, even the God of such who are Israelites indeed; though he should, as he would, give up the present generation to ruin and destruction; they having by their sins forfeited his care and protection of them; and therefore it was in vain to hope for it from this character which they bore: behold, I will turn back the weapons of war that [are] in your hands;
so that they should do no hurt to the enemy, but recoil upon themselves. The meaning is, that they should be useless and unserviceable; that they should neither be defensive to them, nor offensive to their enemies; but rather hurtful to themselves. It seems to suggest, as if they should fall out with one another; and, like the Midianites, turn their swords upon one another, and destroy each other: wherewith ye fight against the king of Babylon, and [against] the
Chaldeans which besiege you without the walls;
by shooting arrows at them from within the city; or by sallying out unto them with sword in hand: this, shows that the Chaldean army, under the command of the king of Babylon, was now without the walls of Jerusalem besieging it: and I will assemble them into the midst of this city;
either the weapons of war, as Jarchi and others; which the Chaldeans, breaking into the city, should cause to be brought in to them in the middle of the city, and there slay them with them: or rather the Chaldeans, as Kimchi; who, though now without the walls, and which the Jews thought a sufficient security for them; yet should not be long there, but the walls would be broken down, and they should enter the city, and rendezvous their whole army in the midst of it.

Jeremiah 21:4 In-Context

2 They said, "Ask the Lord for us what will happen, because Nebuchadnezzar king of Babylon is attacking us. Maybe the Lord will do miracles for us as he did in the past so Nebuchadnezzar will stop attacking us and leave."
3 But Jeremiah answered them, "Tell King Zedekiah this:
4 'Here is what the Lord, the God of Israel, says: You have weapons of war in your hands to defend yourselves against the king of Babylon and the Babylonians, who are all around the city wall. But I will make those weapons useless. Soon I will bring them into the center of this city.
5 In my anger, my very great anger, I myself will fight against you with my great power and strength.
6 I will kill everything living in Jerusalem -- both people and animals. They will die from terrible diseases.
