In this verse God aggravates their sin of oppression, mentioned in the former. As a fountain casteth out her waters, so she casteth out her wickedness; a metaphor, to express how natural all manner of wickedness is to her, how full she is of it, and how incessant in it, noting her impudence, a fountain being not able to retain its water; and the expression of casting it out seems to imply her violence in her filthiness, as it is said of the sea, that it casteth out mire and dirt, Isaiah 57:20, and favoured by the next clause. Violence and spoil is heard in her: q.d. This is all she busieth herself about, Jeremiah 20:8. It is the general complaint of her inhabitants. Before me continually is grief and wounds, viz. that the poor sustain: wherever I go or look, I can hear and see nothing but the sad complaints and grievances of the poor, lamenting over oppression and cruelties that are used against them, Psalms 69:26, this being so expressly against God's command, Exodus 22:22-24, &c.; Isaiah 3:14,15 Jas 5:4; for this refers rather to their sin than to their sufferings from the enemy, as some would carry it.
