Agabus in Fausset's Bible Dictionary

(from Hebrew agab, "he loved".) A Christian prophet (Acts 9:28; Acts 21:10). He came from Judaea to Antioch while Paul and Barnabas were there, and foretold the famine which occurred the next year in Israel (for a Jew would mean the Jewish world, by "throughout all the world.".) Josephus records that Helena, queen of Adiabene, a proselyte then at Jerusalem, imported provisions from Egypt and Cyprus, wherewith she saved many from starvation. The famine was in the procuratorship of Cuspius Fadus and Tiberius Alexander, A.D. 44, and lasted four years. In the wider sense of "the world," as the prophecy fixes on no year, but "in the days of Claudius Caesar," it may include other famines elsewhere in his reign, one in Greece, two in Rome.
