C. F. Keil and Franz Delitzsch on 2 Kings 10:6-7

2Ki 10:6-7

Jehu then wrote them a second letter, to say that if they would hearken to his voice, they were to send to him on the morrow at this time, to Jezreel, the heads of the sons of their lord; which they willingly did, slaying the seventy men, and sending him their heads in baskets. אד בּני אנשׁי ראשׁי, “the heads of the men of sons of your lord,” i.e., of the male descendants of Ahab, in which אנשׁי may be explained from the fact that בּני־אדניכם has the meaning “royal princes” (see the similar case in Jdg 19:22). In order to bring out still more clearly the magnitude of Jehu’s demand, the number of the victims required is repeated in the circumstantial clause, “and there were seventy men of the king’s sons with (את) the great men of the city, who had brought them up.”
