'Threshing floors' in the Bible

Now they told David, "Look, [the] Philistines [are] fighting in Keilah and they [are] raiding the threshing floors."

Do not rejoice, Israel, do not exult like the nations! For you played the whore, departing from your God; you loved a harlot's wage on all the threshing floors of grain.

The threshing floors will be full [with] grain, and the vats will overflow [with] new wine and olive oil.
