They; i.e. the prophets and priests. Wandered as blind men. The leaders of the people are blinded by ignorance, for they know not the only true way of averting calamity, and by passion, for they have not that "eye" of the soul (Matthew 6:22, Matthew 6:23) which alone enables a man to see the good and the right course for himself individually, The" wandering," or, rather, "staggering" (comp.
Psalms 107:27, Authorized Version), however, may also refer to the panic stricken condition of those self. deceived deceivers when overtaken by God's punishment; comp. "wine of reeling" (Authorized Version, "astonishment"), Psalms 60:3; also the prophecies in Deuteronomy 28:28, Deuteronomy 28:29; Jeremiah 23:12.
The doubt is whether "have wandered" refers to some period before the final catastrophe, or to the consternation produced by that awful surprise. The latter view seems the more probable. They have polluted themselves, etc.
Their acts of violence have been continued to the very end of their term of power. Their garments are still stained with blood when the summons to depart into exile reaches them.
