Adam Clarke on Jeremiah 43:7

Came they even to Tahpanhes - This city was called Daphne by the Greeks, and was situated at the extremity of Lower Egypt, near to Heliopolis. It was called Daphne Pelusiaca. They halted at this place, most probably for the purpose of obtaining the king's permission to penetrate farther into Egypt. It was at this place that, according to St. Jerome, tradition says the faithful Jeremiah was stoned to death by these rebellious wretches; for whose welfare he had watched, prayed, gone through many indignities, and suffered every kind of hardship. And now he sealed the truth of his Divine mission with his blood.
