Acts 11:28 (ESV)

28 And one of them named Agabus stood up and foretold by the Spirit that there would be a great famine over all the world (this took place in the days of Claudius).

A famine refers to a lack of food, a time when there is a severe shortage of grain caused by local or provincial harvest failure. Extrabiblical history confirms that there was a food crisis in Egypt, Syria, Judea and Greece in the years AD 45-48.1
