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

8:3 And the songs of the temple shall be howlings in that day, saith the Lord GOD: there shall be many dead bodies in every place; they shall cast them forth with silence.
