2 Samuel 13:34-38

34And Absalom fled. And the young man that watched lifted up his eyes and looked, and behold, there came much people from the way behind him, from the hill-side.

35And Jonadab said to the king, Behold, the king's sons come: as thy servant said, so it is.

36And as soon as he had ended speaking, behold, the king's sons came, and lifted up their voice and wept; and the king also and all his servants wept very bitterly.

37And Absalom fled, and went to Talmai, the son of Ammihud, king of Geshur. And [David] mourned for his son every day.

38Now Absalom fled, and went to Geshur, and was there three years.
