1. The poor were ignorant, and therefore they were wicked. He found many that refused to return, for whom he was willing to make the best excuse their case would bear, and it was this (v. 4): "Surely, these are poor, they are foolish. They never had the advantage of a good education, nor have they wherewithal to help themselves now with the means of instruction. They are forced to work hard for their living, and have no time nor capacity for reading or hearing, so that they know not the way of the Lord, nor the judgments of their God; they understand neither the way in which God by his precepts will have them to walk towards him nor the way in which he by his providence is walking towards them." Note, (1.) Prevailing ignorance is the lamentable cause of abounding impiety and iniquity. What can one expect but works of darkness from brutish sottish people that know nothing of God and religion, but choose to sit in darkness? (2.) This is commonly a reigning sin among poor people. There are the devil's poor as well as God's, who, notwithstanding their poverty, might know the way of the Lord, so as to walk in it and do their duty, without being book-learned; but they are willingly ignorant, and therefore their ignorance will not be their excuse.
