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

8:14 They that swear by the sin of Samaria, and say, Thy god, O Dan, liveth; and, The manner of Beersheba liveth; even they shall fall, and never rise up again.
