1 Samuel 31:13 - Joseph Benson’s Commentary on the Old and New Testaments

And fasted seven days To testify their sorrow for the loss of Saul, and of the people of God; and to entreat God's favour to prevent the utter extinction of his people. But we must not understand this word of fasting strictly, as if they ate nothing for seven whole days; but in a more large sense, as it is used both in sacred and profane writers; that they did eat but little, and that but mean food, and drank only water for that time. This book began with the birth of Samuel, and ends with the death of Saul. The comparing these together will teach us to prefer the honour that comes from God before all the honours of the world. The reader will do well to observe also that in this book we have two such examples of piety and virtue in Samuel and David as we cannot too frequently make the subject of our consideration. On the other hand, in the example of Saul we have a picture of the miserable state of that man who forgetteth God, and turneth aside from his commandments. May God, through Jesus Christ, send down his grace into our hearts, that, through our whole lives, we may be inclined to imitate the first, and may always dread to fall into the state of the latter, and, as the only way to escape it, make it our chief study and delight to please God, and do his will; for this is the whole of man: in which all his happiness, all his peace consists. For that there is no peace to the wicked, hath been pronounced by Him who knoweth the nature and frame of man; by the Lord himself, who cannot lie. “The wicked are like the troubled sea when it cannot rest. There is no peace, saith my God, to the wicked,” Isaiah 57:20-21.
