As the whirlwind passeth - As tornadoes that sweep every thing away before them; so shall the wrath of God sweep away the wicked; it shall leave him neither branch nor root. But the righteous, being built on the eternal foundation, עולם יסוד yesod olam, shall never be shaken.
Or, when the whirlwind is passing, then the wicked is no more. Compare Matthew 7:24-27.
The righteous - In the later rabbinic interpretation this was applied to the Messiah as being the Just One, the Everlasting Foundation, on whom the world was established.
