They have wandered as blind men in the streets, they have polluted themselves with blood, so that men could not touch their garments.
They have wandered as blind - with mental aberration. They have polluted themselves with blood - both with blood of one another mutually shed-for instance, with "the blood ... of the poor innocents" slain to Moloch (Jeremiah 2:34) - and with their blood shed by the enemy (Glassius). So that men could not touch their garments - as being defiled with blood (Numbers 19:16).
