'Stale' in the Bible

When Gideon arrived, he heard a man telling another man about a dream he had. The man said, "Look! I had a dream. I saw a stale cake of barley bread rolling into the Midianite camp. It hit a tent so hard it knocked it over and turned it upside down. The tent just collapsed."

For there is no good tree which produces bad fruit, nor, on the other hand, a bad tree which produces good fruit.
