Ezra 5:8
Let it be known to the king that we went into the province of Judah, to the house of the great God. The people are rebuilding it with large stones, and placing timbers in the walls. This work is being carried out diligently and is prospering in their hands.

For the stones will cry out from the wall, and the rafters will echo it from the woodwork.
