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 6

6:2 Pass ye unto Calneh, and see; and from thence go ye to Hamath the great: then go down to Gath of the Philistines: be they better than these kingdoms? or their border greater than your border?
