'Windblown' in the Bible

Do you wish to torment a windblown leaf and chase after dry chaff?

I grind them as fine windblown dust; I beat them underfoot like clay in the streets.

Who stirs up this one from the east? Who officially commissions him for service? He hands nations over to him, and enables him to subdue kings. He makes them like dust with his sword, like windblown straw with his bow.

before God's decree becomes reality and the day of opportunity disappears like windblown chaff, before the Lord's raging anger overtakes you -- before the day of the Lord's angry judgment overtakes you!
