34. Then Jacob gave. Although, at first sight, this statement seems to be cold and superfluous, it is nevertheless of great weight. For, in the first place, Moses commends the piety of holy Jacob, who in aspiring to a heavenly life, was able to bridle the appetite for food. Certainly he was not a log of wood; in preparing the food for the satisfying of his hunger, he would the more sharpen his appetite. Wherefore he must of necessity do violence to himself in order to bear his hunger. But he would never have been able in this manner to subdue his flesh, unless a spiritual desire of a better life had flourished within him. On the other side, the remarkable indifference of his brother Esau is emphatically described in few words, he did eat and drink, and rose up and went his way. For what reason are these four things stated? Truly, that we may know what is declared immediately after, that he accounted the incomparable benefit of which he was deprived as nothing. The complaint of the Lacedemonian captive is celebrated by the historians. The army, which had long sustained a siege, surrendered to the enemy for want of water. After they had drunk out of the river, O comrades, (he exclaimed,) for what a little pleasure have we lost an incomparable good! He, miserable man, having quenched his thirst, returned to his senses, and mourned over his lost liberty. But Esau having satisfied his appetite, did not consider that he had sacrificed a blessing far more valuable than a hundred lives, to purchase a repast which would be ended in half an hour. Thus are all profane persons accustomed to act: alienated from the celestial life, they do not perceive that they have lost anything, till God thunders upon them out of heaven. As long as they enjoy their carnal wishes, they cast the anger of God behind them; and hence it happens that they go stupidly forward to their own destruction. Wherefore let us learn, if, at any time, we, being deceived by the allurements of the world, swerve from the right way, quickly to rouse ourselves from our slumber.
