'Threshing floors' in the Bible

Then they told David, saying, “Behold, the Philistines are fighting against Keilah and are plundering the threshing floors.”

Then the iron, the clay, the bronze, the silver and the gold were crushed all at the same time and became like chaff from the summer threshing floors; and the wind carried them away so that not a trace of them was found. But the stone that struck the statue became a great mountain and filled the whole earth.

The threshing floors will be full of grain,And the vats will overflow with the new wine and oil.
