"Amos was from Tekoa (1:1), a small town about 6 miles south of Bethlehem and 11 miles from Jerusalem. He was not a man of the court like Isaiah, or a priest like Jeremiah. He earned his living from the flock and the sycamore-fig grove (1:1; 7:14-15). Whether he owned the flocks and groves or only worked as a hired hand is not known. His skill with words and the strikingly broad range of his general knowledge of history and the world preclude his being an ignorant peasant. Though his home was in Judah, he was sent to announce God's judgment on the northern kingdom (Israel). He probably ministered for the most part at Bethel (7:10-13; see note on Ge 12:8), Israel's main religious sanctuary, where the upper echelons of the northern kingdom worshiped."
