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

7:16 Now therefore hear thou the word of the LORD: Thou sayest, Prophesy not against Israel, and drop not thy word against the house of Isaac.
