Agabus

A "prophet," probably one of the seventy disciples of Christ. He prophesied at Antioch of an approaching famine (Acts 11:27,28). Many years afterwards he met Paul at Caesarea, and warned him of the bonds and affliction that awaited him at Jerusalem should he persist in going thither (Acts 21:10-12).
