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 8

8:2 And he said, Amos, what seest thou? And I said, A basket of summer fruit. Then said the LORD unto me, The end is come upon my people of Israel; I will not again pass by them any more.
