Albert Barnes Commentary Jeremiah 2:16

"The children also of Memphis and Tahpanhes have broken the crown of thy head." — Jeremiah 2:16 (ASV)

Noph, that is, Napata, a town situated in the extreme south of Egypt. Some take it to be Memphis (see Isaiah 19:13 note).

Tahapanes – Daphne Pelusii, a border town toward Palestine.

Have broken the crown of your head – literally, shall graze upon the crown of your head; that is, make it bald. Baldness was accounted by the Jews a sign of disgrace (2 Kings 2:23) and also a mark of mourning (Isaiah 15:2; Isaiah 22:12). The Egyptians, in slaying Josiah and capturing Jerusalem, brought ruin, disgrace, and sorrow upon the Jews.
