JETS 39:2 (June 1996) p. 208 Torrey’s own solution, developing an earlier conjecture by F. Hommel, was to trace har magedōn to the Hebrew har môʿēd (cf. Isa 14:13), “Mount of Assembly.” He noted the appropriate association of har môʿēd with Jerusalem and dealt with the question of transcriptional equivalence. The apparent differences between the Hebrew har môʿēd and the har magedōn rendering can be readily accounted for. Representation of the consonant ʿayin by Greek gamma is well attested.
