The name Ashhur (אַשְׁחוּר) appears in 1 Chronicles 2:24 and 4:5 as the 'father of Tekoa' — meaning either the literal founder or the primary ancestor/patron of the city of Tekoa, a town in the highlands of Judah about 6 miles south of Bethlehem.
Tekoa's significance extends far beyond its founder's genealogy. It was the home of the wise woman of Tekoa who helped Joab persuade David to allow Absalom's return (2 Samuel 14). Most significantly, it was the hometown of the prophet Amos — 'a shepherd from Tekoa' (Amos 1:1) who declared God's word against social injustice and religious hypocrisy in the 8th century BC. Ashhur as 'father of Tekoa' is the genealogical root of a city that would produce prophetic witness to power.
