Agabus

Two persons by this name appear in the book of Acts, both of whom are remembered for their prdictions of what would later happen. The first hailed from the church in Antioch, who predicted the famine which swept through the Roman Empire in the reign of Claudius, and which goaded the wider church to raise up support for the church in Judea (Acts 11:28-30, NIV):

During this time some prophets came down from Jerusalem to Antioch. One of them, named Agabus, stood up and through the Spirit predicted that a severe famine would spread over the entire Roman world. (This happened during the reign of Claudius.) The disciples, as each one was able, decided to provide help for the brothers and sisters living in Judea. This they did, sending their gift to the elders by Barnabas and Saul.

The second "came down from Judea" to Caesarea—where Paul and his company was staying with Philip at the end of their "third missionary journey—and predicted Paul's capitivity (Acts 21:7-15, NIV):

We continued our voyage from Tyre and landed at Ptolemais, where we greeted the brothers and sisters and stayed with them for a day. Leaving the next day, we reached Caesarea and stayed at the house of Philip the evangelist, one of the Seven. He had four unmarried daughters who prophesied. After we had been there a number of days, a prophet named Agabus came down from Judea. Coming over to us, he took Paul's belt, tied his own hands and feet with it and said, "The Holy Spirit says, 'In this way the Jewish leaders in Jerusalem will bind the owner of this belt and will hand him over to the Gentiles.'" When we heard this, we and the people there pleaded with Paul not to go up to Jerusalem. Then Paul answered, "Why are you weeping and breaking my heart? I am ready not only to be bound, but also to die in Jerusalem for the name of the Lord Jesus." When he would not be dissuaded, we gave up and said, "The Lord's will be done." After this, we started on our way up to Jerusalem.
