NET

21 He was driven from human society; his mind was changed to that of an animal. He lived with the wild donkeys, he was fed grass like oxen, and his body became damp with the dew of the sky, until he came to understand that the most high God rules over human kingdoms, and he appoints over them whomever he wishes.

Darby

21 and he was driven from the sons of men, and his heart was made like the beasts, and his dwelling was with the wild asses; they fed him with grass like oxen, and his body was bathed with the dew of heaven; till he knew that the Most High God ruleth over the kingdom of men, and that he appointeth over it whomsoever he will.

KJV

21 And he was driven from the sons of men; and his heart was made like the beasts, and his dwelling [was] with the wild asses: they fed him with grass like oxen, and his body was wet with the dew of heaven; till he knew that the most high God ruled in the kingdom of men, and [that] he appointeth over it whomsoever he will.
