2 Samuel 19:1

And the king was troubled, and went to the chamber over the gate, and wept: and thus he said as he went, My son Abessalom, my son, my son Abessalom; would God I had died for thee, [even] I [had died] for thee, Abessalom, my son, my son!

And it was told Joab, Behold, the king weepeth and mourneth for Absalom.

Joab was told, “Behold, the king weeps and mourns for Absalom.”
