“Why, you have it here in so many words: Look, these are sinners, and prospering always; they have become rich. "Is it to no purpose that I set my heart right or washed my hands among the innocent and was scourged every day?" I worship God; they blaspheme God. For them good fortune, for me misfortune. Where is the justice of it? That is why feet were shaken, that is why steps were almost pulled from under, that is why destruction was looming. Yes, just notice please what a dangerous position he had got into. He adds, "And I said, How did God know? Can there be knowledge in the most High?" Notice what a dangerous position he has got into by looking for earthly good fortune from God as though it were of great value.”

“Behold, these are the ungodly,.... Who say and do as before declared; such as these must be without the knowledge of God, the fear, love, and worship of him: who prosper in the world; in worldly and temporal things, in their bodies and outward estates, but not in their souls and spiritual things: "in this world", as the Targum is; all their prosperity is here; their good things are in this life, their evil things will be in that to come; though ungodly, they prosper in the world, and as long as they are in it; or they are at peace and in case, and are quiet; they have nothing to disturb them, they are not in outward trouble, and their sins do not distress them, and they have no concern about another world: they increase in riches; which they are in the pursuit of, and overtake and enjoy in great abundance; whereby they become mighty and powerful, as the word (o) for "riches" signifies: these words are the observation of the psalmist, and which was the occasion of the following temptation he was led into. (o) "vires", Junius & Tremellius; "potentiam", Piscator.”
