Book of Amos
Amos lived during the time of two other prophets,Hosea and Isaiah, around 750 BC while Jeroboam was king of Israel and Uzziah was king of Judah. Amos lived in the kingdom of Judah but preached in the northern Kingdom of Israel. He wrote about social justice, God's power, judgement and eventual restoration. The message is harsh, but Amos wrote some of the most poetic parts of the Bible.
