Thematic Bible: Who God gives wisdom to

There is nothing better for man than to eat, drink, and to enjoyhis work. I have seen that even this is from God's hand. For who can eat and who can enjoy life apart from Him? For to the man who is pleasing in His sight, He gives wisdom, knowledge, and joy, but to the sinner He gives the task of gathering and accumulating in order to give to the one who is pleasing in God's sight. This too is futile and a pursuit of the wind.

and declared: May the name of God be praised forever and ever, for wisdom and power belong to Him. He changes the times and seasons; He removes kings and establishes kings. He gives wisdom to the wise and knowledge to those who have understanding.

Daniel determined that he would not defile himself with the king's food or with the wine he drank. So he asked permission from the chief official not to defile himself. God had granted Daniel favor and compassion from the chief official, yet he said to Daniel, "My lord the king assigned your food and drink. I'm afraid [of what would happen] if he saw your faces looking thinner than those of the other young men your age. You would endanger my life with the king." read more.
So Daniel said to the guard whom the chief official had assigned to Daniel, Hananiah, Mishael, and Azariah, "Please test your servants for 10 days. Let us be given vegetables to eat and water to drink. Then examine our appearance and the appearance of the young men who are eating the king's food, and deal with your servants based on what you see." He agreed with them in this matter and tested them for 10 days. At the end of 10 days they looked better and healthier than all the young men who were eating the king's food. So the guard continued to remove their food and the wine they were to drink and gave them vegetables. God gave these four young men knowledge and understanding in every kind of literature and wisdom. Daniel also understood visions and dreams of every kind.
