Woe to thee, O land, when thy king [is] a child,.... Not so much in age; though it is sometimes an unhappiness to a nation to be governed by a minor, especially if the young king has not good tutors, guardians, ministers, and counsellors, about him; but, if otherwise, a nation may be very happy under a minority, or the government of a young prince; such were Solomon, Joash, Uzziah, Josiah, and our Edward VI: but it rather respects one that is a child in understanding and judgment, in manners and conduct; that minds his pleasures, as children their play; is fickle and changeable, passionate and self-willed, unskilful in government, and yet will not be advised.
The Targum applies this to the land of Israel, and instances in wicked Jeroboam, who made the morning sacrifice to cease; see Isa 3:12. From considering the bad effects of folly in men in general, in private persons and in subjects, the wise man proceeds to observe the ill consequences of it to a nation, in kings and princes, in civil magistrates: Jerom or Bede interprets this allegorically: Woe to the land whose king is the devil, who is always desirous of new things, 2Co 4:4;and thy princes eat in the morning; as soon as they are up, children like; and not only eat, which may be convenient and lawful to do; but eat to excess, in a riotous and intemperate manner, and so unfit themselves for any service all the day: the "morning" is particularly observed, because the fittest time for consultation about the affairs of government; and was the usual time of sitting in judgment and trying causes, Jer 21:12; and also for acts of religion and devotion.
And so the Targum,"and thy princes eat bread before they offer the daily morning sacrifice.'
