Who said this: “Please test us for ten days on a diet of vegetables and water...? - BIBLE QUIZ

Who said this: “Please test us for ten days on a diet of vegetables and water. At the end of the ten days, see how we look compared to the other young men who are eating the King's food." ?

— Answer: C Daniel

The most significant thing about Daniel - The Bible gives us zero dirt on Daniel! 

Abraham had his Hagar incident.
Moses struck the rock and was banned from Canaan.
David committed adultery and murder.
And those other two sterling examples of righteousness, Noah and Job? Noah got drunk and naked (Genesis 9:21). Even Job repented because of how he spoke about God (Job 38:2; 42:1–6).

But Daniel?

We have nothing on Daniel.
In fact, when his political opponents tried to get dirt on him, their only option was to make it illegal to obey God (Daniel 6:4–5).
