When We decreed death for him (Solomon), nothing showed his death to the Wild Tribes until a creature of the earth ate away the strength he had mustered. When the power base fell, the Wild Tribes rebelled regretting that they should have done it sooner only if they knew the new unjust King. (The 'creature of the earth' was the highly incompetent son Rehoboam, and successor of Solomon 38:34. Historically, ten of the Israelite Tribes also broke away from the Kingdom at that point).
