Ps 82:13

“What does he mean by this? As I take it, that goodness can with difficulty gain a hold on human nature, like fire on green wood; while most people are ready and disposed to join in evil, like stubble, I mean, ready for a spark and a wind, which is easily kindled and consumed from its dryness. For a person will engage more quickly and fully in evil with the slightest inducement than in good with only little encouragement.”

“"O my God, make them like a wheel." Notice the mercy of the prophet; he does not pray against them but for them. See what he says: My God, who is the God of all, my very own God, O my God, make them like a wheel. They who lay their foundation in malice, let them have no foundation at all, but let them roll back and forth and never remain fixed in their malice.”

“But what follows? "My God, make them like a wheel" [Psalm 83:13]. This is fitly taken as meaning that they should be constant in nothing that they think; but I think it may also be rightly explained, make them like a wheel, because a wheel is lifted up on the part of what is behind, is thrown down on the part of what is in front; and so it happens to all the enemies of the people of God. For this is not a wish, but a prophecy. He adds: "as the stubble in the face of the wind." By face he means presence; for what face has the wind, which has no bodily features, being only a motion, in that it is a kind of wave of air? But it is put for temptation, by which light and vain hearts are hurried away.”
