rent his clothes] To signifie the rending of his heart with grief and anguish. See Gen. 37. 29, 34. not for that small defeat, but because it was a signe of Gods wrath, seeing he prospered not their expedition according to former promises, which might discourage the people, and make them faint-hearted, as v 5.
before the ark] In these difficulties fleeing unto God, as his onely refuge, for counsell and direction. See Chap. 9. 14.
put dust] A ceremony used in great mournings. So 1 Samuel 4:12. 2 Samuel 13:19. Nehemiah 9:1. Job 2:12.
