Pathros
Easton's Dictionary
The name generally given to Upper Egypt (the Thebaid of the Greeks), as distinguished from Matsor, or Lower Egypt (Isa. 11:11; Jer. 44:1, 15; Ezek. 30:14), the two forming Mizraim. After the destruction of Jerusalem by Nebuchadnezzar, colonies of Jews settled “in the country of Pathros” and other parts of Egypt.
Smith's Dictionary
(region of the south), a part of Egypt, and a Mizraite tribe whose people were called Pathrusim. In the list of the Mizraites the Pathrusim occur after the Naphtuhim and before the Caluhim; the latter being followed by the notice of the Philistines and by the Caphtorim. (Genesis 10:13,14; 1 Chronicles 1:12) Pathros is mentioned in the prophecies of Isaiah, (Isaiah 11:11) Jeremiah (Jeremiah 44:1,15) and Ezekiel. (Ezekiel 29:14; 30:13-18) It was probably part or all of upper Egypt, and we may trace its name in the Pathyrite name, in which Thebes was situated.
