Oracle Against Jerusalem

In that day you depended on the weapons of the house of the forest,
⁹ And you saw that the breaches
In the wall of the city of David were many;
And you collected the waters of the lower pool.
¹⁰ Then you counted the houses of Jerusalem
And tore down houses to fortify the wall.
