KJV:
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.
NASB:
"He was also driven away from mankind, and his heart was made like that of beasts, and his dwelling place was with the wild donkeys. He was given grass to eat like cattle, and his body was drenched with the dew of heaven until he recognized that the Most High God is ruler over the realm of mankind and that He sets over it whomever He wishes.
