Also {g} Amaziah said unto Amos, O thou seer, go, flee thee away into the land of Judah, and there eat bread, and prophesy there:

(g) When this instrument of Satan was not able to accomplish his purpose by the king, he tried by another practice, that was, to scare the Prophet, that he might depart, and not reprove their idolatry there openly, and so hinder his profit.

Jamieson-Fausset-Brown Bible Commentary

12. Also-Besides informing the king against Amos, lest that course should fail, as it did, Amaziah urges the troublesome prophet himself to go back to his own land Judah, pretending to advise him in friendliness.

seer-said contemptuously in reference to Amos' visions which precede.

there eat bread-You can earn a livelihood there, whereas remaining here you will be ruined. He judges of Amos by his own selfishness, as if regard to one's own safety and livelihood are the paramount considerations. So the false prophets (Eze 13:19) were ready to say whatever pleased their hearers, however false, for "handfuls of barley and pieces of bread."

Matthew Henry's Concise Commentary

7:10-17 It is no new thing for the accusers of the brethren, to misrepresent them as enemies to the king and kingdom, as traitors to their prince, and troublers of the land, when they are the best friends to both. Those who make gain their godliness, and are governed by the hopes of wealth and preferment, are ready to think these the most powerful motives with others also. But those who have a warrant from God, like Amos, ought not to fear the face of man. If God, that sent him, had not strengthened him, he could not thus have set his face as a flint. The Lord often chooses the weak and foolish things of the world to confound the wise and mighty. But no fervent prayers, or self-denying labours, can bring proud sinners to bear faithful reproofs and warnings. And all who oppose or despise the Divine word, must expect fatal effects to their souls, unless they repent.
