Tonight we are winnowing barley on the threshing-floor.

There are two similies: "like a whirlwind" and "like the chaff of the summer threshing floor".
It measns that king David bought a threshing floor for 50 shekels of silver and then built an altar there.
Threshing was done by beating the grain using a flail on a threshing floor or by making donkeys or oxen walk in circles on the grain on a hard surface. A flail is a tool used for threshing. It is made from two or more large sticks attached by a short chain; one stick is held and swung, causing the other to strike a pile of grain, loosening the husks.
Threshing is a term used in the process of refining grain. In the Bible people had "threshing floors" The wheat or other grain had to be separated from the stalks. This was done by beating (Threshing) the grain stalks until the grain fell free.
