Easton's Bible Dictionary (1897)
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 Bible Dictionary (1863)
(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.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
PATH'ROS (region of the south), a district of Egypt near Thebes; named, as some suppose, from a town called Ha-hathor, or "the abode of Hathor," the Egyptian Venus. Originally it was ruled by its own kings, independent of Egypt. It was probably the Thebaid of the Greeks and the Said of the Arabs. The country is mentioned in the Prophets, and nearly always in connection with Egypt. Isa 11:11; Isa 19:11-13; Jer 44:1-15; Eze 29:14. Its inhabitants
were known as the Pathrusim, the descendants of Ham through Mizraim. Gen 10:14; 1 Chr 1:12.
Hitchcock's Bible Names (1869)
