Refreshing Daniel

.....he giveth wisdom unto the wise, and knowledge to them that know understanding:
Daniel 2:21
"Daniel was an intellectual giant; yet he was continually seeking for greater knowledge,..other young men,...did not, like him, bend all their energies to seek wisdom-the knowledge of God. He felt the need of refreshing his soul with prayer."
