Jeremiah 1:18

1:18 I, the Lord, hereby promise to make you as strong as a fortified city, an iron pillar, and a bronze wall. You will be able to stand up against all who live in the land, including the kings of Judah, its officials, its priests and all the people of the land.

Jeremiah 5:17

5:17 They will eat up your crops and your food.

They will kill off your sons and your daughters.

They will eat up your sheep and your cattle.

They will destroy your vines and your fig trees.

Their weapons will batter down

the fortified cities you trust in.

Jeremiah 8:14

Jeremiah Laments over the Coming Destruction

8:14 The people say,

“Why are we just sitting here?

Let us gather together inside the fortified cities.

Let us at least die there fighting,

since the Lord our God has condemned us to die.

He has condemned us to drink the poison waters of judgment

because we have sinned against him.

Jeremiah 34:7

34:7 He did this while the army of the king of Babylon was attacking Jerusalem and the cities of Lachish and Azekah. He was attacking these cities because they were the only fortified cities of Judah which were still holding out.
