Midrasch zu Mischlej 15:19

Solomon exclaimed: The way of the sluggard is as though hedged by thorns; but the path of the upright is even (Prov. 15:19). Scripture is referring in this verse to the wicked Esau. Just as the thorns from a bush that cling to a man’s garment will cling to another part of the garment when he tries to brush them off, so the government of Esau (Rome), while still collecting a crop tax from Israel, would impose a head tax. And even before the head tax was fully collected, it would impose a levy for the care of its soldiers. The Holy One, blessed be He, did not do that: For the path of the upright is even, made level before Israel.
