24 Now Mephibosheth, Saul's grandson, came down from Jerusalem to meet the king. He had not cared for his feet, trimmed his beard, or washed his clothes since the day the king left Jerusalem.

Matthew Henry's Commentary on 2 Samuel 19:24

Commentary on 2 Samuel 19:24-30

(Read 2 Samuel 19:24-30)

David recalls the forfeiture of Mephibosheth's estate; and he expressed joy for the king's return. A good man contentedly bears his own losses, while he sees Israel in peace, and the Son of David exalted.
