II. The cause of this judgment assigned. It is all for their wickedness; they have brought it upon themselves; they must bear it, for they must bear the blame of it. They are thus oppressed because they have been oppressors; they have dealt hardly with one another, each in his turn, as they have had power and advantage, and now the enemy shall come and deal hardly with them all. This sin of oppression, and violence, and wrong-doing, is here charged upon them, 1. As a national sin (v. 6): Therefore this city is to be visited, it is time to make inquisition, for she is wholly oppression in the midst of her. All orders and degrees of men, from the prince on the throne to the meanest master of a shop, were oppressive to those that were under them. Look which way you might, there were causes for complaints of this kind. 2. As a sin that had become in a manner natural to them (v. 7): She casts out wickedness, in all the instances of malice and mischievousness, as a fountain casts out her waters, so plentifully and constantly, the streams bitter and poisonous, like the fountain. The waters out of the fountain will not be restrained, but will find or force their way, nor will they be checked by laws or conscience in their violent proceedings. This is fitly applied to the corrupt heart of man in his natural state; it casts out wickedness, one evil imagination or other, as a fountain casts out her waters, naturally and easily; it is always flowing, and yet always full. 3. As that which had become a constant practice with them; Violence and spoil are heard in her. The cry of it had come up before God as that of Sodom: Before me continually are grief and wounds—the complaint of those that find themselves aggrieved, being unjustly wounded in their bodies or spirits, in their estates or reputation. Note, He that is the common Parent of mankind regards and resents, and sooner or later will revenge, the mischiefs and wrongs that men do to one another.
