The book of Amos provides background on the prophet Amos, who originated from Tekoa and worked as a herdman. Amos prophesied during the reign of kings Uzziah of Judah and Jeroboam II of Israel around 776-763 BC. Amos pronounces God's judgment on various nations, including Israel and Judah. God is angry due to the nations' religious hypocrisy, luxury, and mistreatment of the poor. Amos receives three visions from God involving locusts, fire, and a plumb line. The book describes God's coming judgment but also a future promise of restoration.
