DANIEL 1:12
 

“Please test your servants for ten days, and let them give us vegetables to eat and water to drink. [Daniel 1:12 NKJV]
 

Daniel said to the guard, “Please give us this test for ten days: Don’t give us anything but vegetables to eat and water to drink. [Daniel 1:12 ICB]

Daniel here requested the security manager in charge over him and his three brethren, to kindly conduct a "Mock Exam" or "Mock Test/Trial" for the four of them over a period of one and half (1½) weeks. During the trial, he was to feed them only vegetables and water, to prove them for ten days.
 

Mock exams are designed to replicate the timing and structure of the main exam. In this sense or application, the word "Mock" means "Mimic, Immitate, Replicate or Simulate" the main or original thing. So if that was to be a Mock Exam/Test, then surely there was going to be the main Exam or Test that mattered to life or death.
 

Daniel, in the Bible verse above, proposed and requested the security manager over him to do "Mock Exam" for him and his company of three. That was a very wise engagement able to resolve the doubts and fears, for by that shall the evidence or result prove the worthiness of Daniel's bid.
 

But do not mistake the "Mock Exam" for the "Probation Period:"
 

***** The Probation Period was Ten Days, comprising in feeding as Vegans/Vegetarians only, as suggested by Daniel;
 

***** The Mock Exam proper would be in the next verse, at the end of the ten days, precisely the results or evidence before the Security manager to judge the performance of those four students in Physical and Health Studies [PHS].
 

Thus, this Bible verse above is about Daniel proposing a Probation Period of 10 Days for the employment/application of Vegetables and Water only for the bodies of Daniel, Hananiah, Mishael and Azariah; rather than the employment/application of the food and wine of the king of Babylon to those undefiled bodies. But at the end of the 10 Days, the Mock Exam is not going to prove the Vegetables and Water taken, but prove the men who took them. It's like saying, employ these natural salad and water into the food menu for my sake, and after 10 Days test me, (not testing/tasting the food, but testing me who tasted the food) to prove me; and my performance and outcome should determine either the permanent employment of these food I recommended or the sacking/firing of the food.
 

If that be the case, then I would have become what I ate, and advocated for, by 10 Days, so that my performance at the tenth day is one with the fate of the food I had lived by for those ten days. Thus, at the tenth day, I became what I ate in order to represent what I ate in the sense of Daniel in the Bible verse above: Then to judge me in physical & health wise would automatically be to judge the food I fed or lived by for those 10 Days. Then the food and my belly became one. As it is written,
 

[1 Corinthians 6:13 BSB'19] — "“Food for the stomach and the stomach for food,” but God will destroy them both. The body is not intended for sexual immorality, but for the Lord, and the Lord for the body."
 

Again, it is written,
 

[John 6:27 GLW] — "Don’t labor for perishable food, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.”"
 

In His Holy Communion, the Bread broken with His own Hands (not the bread broken with the hands of pastors and men of God); that Bread broken with His own Hands and given to you to eat in His own Word that pronounced the Bread as His own Body/Flesh — eating that broken and blessed bread representing His broken Body makes your Body one with His Body that already became one with that Bread both you and Him ate.
 

Yes, relate what Daniel was requesting the Security manager to do to them and that which God Himself already did to the children of Israel before their Promised Land as it is written below:
 

[Deuteronomy 8:2‭-‬4 NKJV] — And you shall remember that the Lord your God led you all the way these forty years in the wilderness, to humble you and test you, to know what was in your heart, whether you would keep His commandments or not. So He humbled you, allowed you to hunger, and fed you with manna which you did not know nor did your fathers know, that He might make you know that man shall not live by bread alone; but man lives by every word that proceeds from the mouth of the Lord. Your garments did not wear out on you, nor did your foot swell these forty years.
