J. Lindblom conjectures that Amos “joined the sanctuary staff at Bethel.” Prophecy in Ancient Israel (Oxford, 1962), p. 208. Of the others we know nothing. Some claim on the basis of passages like Isaiah 8:2 that Isaiah was a nobleman, but this is just a guess. Lindblom’s assertion (loc. cit.) that Isaiah “seems to have been a prophet of the non-sacral type” and that “Micah was a man from the country-side, perhaps a small freeholder” falls into the same category.
