2 Samuel 13:38

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

And David mourned for his son every day,] i.e., For his son Amnon. This was a long while to mourn for a lost son - viz, every day for three years' time. The grief was, - (1.) For that he was so basely butchered by his own brother (we had a like example lately here ia England in the family of Sir George Sandys); (2.) For that he died in his drunkenness, having never soundly repented of his incest, though Hugo thinketh he did, and was therefore spared by his father.
