Jeremiah 2:16, or Tahpanhes, Jeremiah 43:7,9, or Tegaphnehes, Ezekiel 30:18, the name of an Egyptian city, for which the Seventy put Taphne, and the Greek historians Daphne. This city lay in the vicinity of Pelusium, towards the southwest, on the western bank of the Pelusiac branch of the Nile, and is therefore called by Herodotus the Pelusiac Daphne. To this city Johanan and many of the Jews retired, after the destruction of Jerusalem by the Chaldeans, taking with them the prophet Jeremiah, Jeremiah 43:7-9 44:1. That Tahapanes was a large and important city, is apparent from the threats uttered against it by Ezekiel 30:18. According to some, Hanes, in Isaiah 30:4, is an abbreviated name of the same city.

Tahapanes
=Tahpanhes=Tehaphnehes, (called "Daphne" by the Greeks, now Tell Defenneh), an ancient Egyptian city, on the Tanitic branch of the Nile, about 16 miles from Pelusium. The Jews from Jerusalem fled to this place after the death of Gedaliah (q.v.), and settled there for a time (Jeremiah 2:16; 43:7; 44:1; 46:14). A platform of brick-work, which there is every reason to believe was the pavement at the entry of Pharaoh's palace, has been discovered at this place. "Here," says the discoverer, Mr. Petrie, "the ceremony described by [Jeremiah 43:8-10; "brick-kiln", i.e., pavement of brick] took place before the chiefs of the fugitives assembled on the platform, and here Nebuchadnezzar spread his royal pavilion" (RSV, "brickwork").
