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 9

9:12 That they may possess the remnant of Edom, and of all the heathen, which are called by my name, saith the LORD that doeth this.
