And reported all; to forewarn them of what they might expect, and encourage them to hope for the like deliverance. Chief priests; to what hath been said concerning them might be added, that these, it may be, were the first or chief in the courses, which David divided the priests into, which division was observed till our Saviour's time, Luke 1:5.
