'Prophesy' in the Bible

"And it shall come to pass in the last days, God says, that I will pour out My Spirit upon all mankind; and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall have dreams;

and even upon My bondservants, both men and women, at that time, I will pour out My Spirit, and they shall prophesy.

and when Paul laid his hands upon them, the Holy Spirit came on them, and they began to speak in tongues and to prophesy.
