two and twenty years. In 1Ki_15:25 Nadab reigned two years, and began in the second year of Asa, which was the twenty-first of Jeroboam, so that Nadab's two years fall within the time of his father's twenty-two. But from 2Ch_13:20 we learn that Jeroboam was stricken with a languishing disease, in which time Nadab reigned with him, and died the same year as his father. The number "twentytwo" is associated with disorganization and disintegration (= 2x11). It is associated with the worst two reigns: Jeroboam, here; and Ahab in 1Ki_16:29.
slept with his fathers = died. See notes on Deu_31:16. Said of the wicked Jeroboam and Ahab, as well as of good David and Jehoshaphat.
