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 5

5:26 But ye have borne the tabernacle of your Moloch and Chiun your images, the star of your god, which ye made to yourselves.
