Amos lived about 750 BCE. He came from the village of Tekoa in Judah where he was a herdsman and a dresser of sycamore trees. Although he came from the south, he prophesied in the northern kingdom, especially at the sanctuary at Bethel. He condemned Israel’s oppression of the poor and said "let justice roll down like waters and righteousness like an everflowing stream" (5:24).
