Holy Spirit gives prophetic insight
Acts 11:27–28 (ASV)
27Now in these days there came down prophets from Jerusalem unto Antioch. 28And there stood up one of them named Agabus, and signified by the Spirit that there should be a great famine over all the world: which came to pass in the days of Claudius.
Acts 21:10–11 (ASV)
10And as we tarried there some days, there came down from Judaea a certain prophet, named Agabus. 11And coming to us, and taking Paul’s girdle, he bound his own feet and hands, and said, Thus saith the Holy Spirit, So shall the Jews at Jerusalem bind the man that owneth this girdle, and shall deliver him into the hands of the Gentiles.
