Not every Ashtaroth is a goddess. In these verses it is a city in Bashan, the kingdom of Og. Moses recalls that Og “dwelt at Astaroth in Edrei,” and Joshua says the half tribe of Manasseh received Ashtaroth along with Gilead and Edrei. Long before that, in Genesis, a group of invading kings struck down the Rephaims at Ashteroth Karnaim. The spellings vary a little, but each verse names a place on the east side of the Jordan. These passages are mostly about land and conquest, and they show how often a single town is mentioned in the story of Israel’s journey. Joshua 13 is a good place to start.

And in the fourteenth year came Chedorlaomer, and the kings that were with him, and smote the Rephaims in Ashteroth Karnaim, and the Zuzims in Ham, and the Emims in Shaveh Kiriathaim,
After he had slain Sihon the king of the Amorites, which dwelt in Heshbon, and Og the king of Bashan, which dwelt at Astaroth in Edrei:
And half Gilead, and Ashtaroth, and Edrei, cities of the kingdom of Og in Bashan, were pertaining unto the children of Machir the son of Manasseh, even to the one half of the children of Machir by their families.
Matthew George Easton, 1897
A city of Bashan, in the kingdom of Og (Deut. 1:4; Josh. 12:4; 13:12; 9:10). It was in the half-tribe of Manasseh (Josh. 13:12), and as a Levitical city was given to the Gershonites (1 Chr. 6:71). Uzzia, one of David’s valiant men (1 Chr. 11:44), is named as of this city. It is identified with Tell Ashterah, in the Hauran, and is noticed on monuments B.C. 1700-1500. The name Beesh-terah (Josh. 21:27) is a contraction for Beth-eshterah, i.e., “the house of Ashtaroth.”
William Smith, 1884
and once As’taroth (a star), a city on the east of Jordan in Bashan, in the kingdom of Og, doubtless so called from being a seat of the worship of the goddess of the same name. (1:4; Joshua 9:10; 12:4; 13:12)
