Charles Ellicott Commentary 2 Samuel 13:19

"And Tamar put ashes on her head, and rent her garment of divers colors that was on her; and she laid her hand on her head, and went her way, crying aloud as she went." — 2 Samuel 13:19 (ASV)

Went on crying. — Literally, went going and cried; that is, as she went away she cried aloud. Tamar put on every external mark of the deep grief within; and this was not only fitting in itself, but was a proper means to obtain justice for her wrongs.
