It is possible that the “Sacred Fire Altar” is related to the “hearth altar” of Ataroth mentioned in line 12 of the Mesha Stele. See Aaron Schade, “‘RYT’ or ‘HYT’ in Line 12 of the Mesha Inscription: A New Examination of the Stele and the Squeeze, and the Syntactic, Literary, and Cultic Implications of the Reading,” Bulletin of the American Schools of Oriental Research 378 (2017), pp. 145–162.
