Amos was a native of the southern kingdom of Judah, from the town of Tekoa -- about six miles south of Bethlehem, twelve miles south of Jerusalem, and eighteen miles west of the Dead Sea. Tekoa was the center for a large sheep farming district and Amos himself was a shepherd until God chose him to deliver some messages.
Amos answered Amaziah, "I was neither a prophet nor a prophet's son, but I was a shepherd, and I also took care of sycamore-fig trees. But the LORD took me from tending the flock and said to me, 'Go, prophesy to my people Israel.'
Under Jeroboam II the kingdom of Israel rose to the peak of its prosperity, but this resulted in decadence, vice and idolatry. Amos was called to remind people of God's law and call them to repentance. Israel rejected his message.
Amos prophesied in the days of Uzziah, king of Judah, and was contemporary with Isaiah and Hosea, who survived him a few years. We do not know what happened to him after he delivered Godís message to the Northern Kingdom. Perhaps he went back to his life in the country as a herdsman and dresser of sycamore trees.
