In the general the prophet threateneth them, that in Egypt they should meet with the very same evils the fear of which made them flee out of their own country, the sword and famine; the sword of Nebuchadnezzar, who, after this, fully conquered Egypt; and a famine through want of bread; for although Egypt was a fruitful country, yet we know there was a famine there, against which Joseph provided; besides that scarcity of victuals commonly followeth great armies. Those who shun dangers, or think to shun them, by acts of disobedience to God, ordinarily are suffered by God to take such courses as they fall into the same or worse dangers than what they labour to avoid.
