John Gill Commentary Daniel 5:16

"But I have heard of thee, that thou canst give interpretations, and dissolve doubts; now if thou canst read the writing, and make known to me the interpretation thereof, thou shalt be clothed with purple, and have a chain of gold about thy neck, and shalt be the third ruler in the kingdom." — Daniel 5:16 (ASV)

Commentary on And I have heard of you: That is, by the queen, which he repeats for the sake of observing what she had said of him, and which gave him encouragement to send for him. Commentary on that you can make interpretations: of dreams, and of things hard to be understood. Commentary on and dissolve doubts: untie knots, solve difficulties, and answer hard and intricate questions.

Commentary on now if you can read the writing, and make known to me the interpretation thereof: that which is upon the wall before you, and which the wise men of Babylon could not. Commentary on you shall be clothed with scarlet, and have a chain of gold about your neck, and shall be the third ruler in the kingdom: the same reward he had proposed to the astrologers and soothsayers, (Daniel 5:7) but what was no temptation or motive to Daniel, as appears by what follows.
