Adam Clarke on Amos 7:12

O thou seer - He pretends kindness to the prophet, and counsels him to go into Judea, and prophesy there and be safe, even in the time that he had accused him of high treason against Jeroboam. Hireling priests of this kind have ever been the great enemies of the true prophets of God; and when they could bring no charge of false doctrine or immorality against them, have accused them of conspiring against the government; and because they have preached against sin, have held them up as exciting insurrection among the people.
