2 Samuel 13:35-37, 37-39

Then Jonadab exclaimed to the king, “See! It’s the king’s sons coming, just as I said!” He had no sooner said the words than the king’s sons burst in—loud laments and weeping! The king joined in, along with all the servants—loud weeping, many tears. David mourned the death of his son a long time.

When Absalom fled, he went to Talmai son of Ammihud, king of Geshur. He was there three years. The king finally gave up trying to get back at Absalom. He had come to terms with Amnon’s death.
