Amos is the book of the herdsman from Tekoa, a small town in Judah. He receives a direct call from God to prophesy against the unrighteousness of both Judah and Israel. Amos is the first prophet to proclaim that God is the ruler of the whole world.

Amos 7

7:2 And it came to pass, that when they had made an end of eating the grass of the land, then I said, O Lord GOD, forgive, I beseech thee: by whom shall Jacob arise? for he is small.
