He wandereth abroad for bread - The Septuagint renders this, “he is destined to be food for vultures” - κατατέτακται δὲ εἰς σῖτα γυψίν katatetaktai de eis sitos gupsin. The meaning of the Hebrew is, simply, that he will be reduced to poverty, and will not know where to obtain a supply for his returning needs.
He knoweth that the day of darkness is ready at his hand - He is assured that the period of calamity is not far remote. It must come. He has no security that it will not come immediately. The whole design of this is to show that there is no calmness and security for a wicked man; that in the midst of apparent prosperity his soul is in constant dread.
