7. Purge me with hyssop, &c.] As the priest is wont to denote unclean persons to be cleansed, by sprinkling them with water mixed with the ashes of an heifer, E 21. These things hast thou done, &c.] All this wickedness hast thou committed, and I have forborne to punish thee; but my forbearance, instead of leading thee to amendment, has made thee consider me, either as ignorant of thy wickedness, or inclined to evil like thyself: but I will now rebuke thee sharply for it, and set all thy evil deeds in order before thine eyes. Bp. Patrick.
