2 Samuel 19: 1 - 3
1 It was told Jo'ab, "Behold, the king is weeping and mourning for Ab'salom."
2 So the victory that day was turned into mourning for all the people; for the people heard that day, "The king is grieving for his son."
3 And the people stole into the city that day as people steal in who are ashamed when they flee in battle.
