'Brick kiln' in the Bible

Then the Lord said to Moses and Aaron, “Take handfuls of soot from the brick kiln, and let Moses throw it toward the sky in the sight of Pharaoh.

And he brought forth the people that were therein, and put them under saws, and under harrows of iron, and under axes of iron, and made them pass through the brickkiln: and thus did he unto all the cities of the children of Ammon. So David and all the people returned unto Jerusalem.

Take great stones in thine hand, and hide them in the clay in the brickkiln, which is at the entry of Pharaoh's house in Tahpanhes, in the sight of the men of Judah;

Draw thee waters for the siege, fortify thy strong holds: go into clay, and tread the morter, make strong the brickkiln.
