Pathros

Pathros refers to Upper Egypt, primarily the Thebaid where it extended from Elephantine fort to modern Asyut north of Thebes. Gardiner argues it extended to the north no further than Abydos. It is mentioned in the Hebrew Bible in Jeremiah 44:1 and 15; Isaiah 11:11; and Ezekiel 29:14, 30:14. It is the homeland of the "Pathrusim".
The name is a loan from Egyptian pꜣ tꜣ-rsj "the southern land" As in Hebrew and Greek, the term was used in Akkadian by the Assyrians as, for example in the Annals of Esarhaddon.
