And the king was much moved, and went up to the chamber over the gate, and wept: and as he went, thus he said, O my son Absalom, my son, my son Absalom! would God I had died for thee, O Absalom, my son, my son!(2 Samuel 18:33)

And it was told Joab, Behold, the king weepeth and mourneth for Absalom.(2 Samuel 19:1)

And the victory that day was turned into mourning unto all the people: for the people heard say that day how the king was grieved for his son.(2 Samuel 19:2)

But the king covered his face, and the king cried with a loud voice, O my son Absalom, O Absalom, my son, my son!(2 Samuel 19:4)

And Joab came into the house to the king, and said, Thou hast shamed this day the faces of all thy servants, which this day have saved thy life, and the lives of thy sons and of thy daughters, and the lives of thy wives, and the lives of thy concubines;(2 Samuel 19:5)

In that thou lovest thine enemies, and hatest thy friends. For thou hast declared this day, that thou regardest neither princes nor servants: for this day I perceive, that if Absalom had lived, and all we had died this day, then it had pleased thee well.(2 Samuel 19:6)
