Daniel 1:9-21

Now God granted Daniel favor and compassion in the sight of the commander of the officials, and the commander of the officials said to Daniel, “I am afraid of my lord the king, who has prearranged your food and your drink; for why should he see your faces looking more haggard than the young men who are your own age? Then you would make me forfeit my head to the king.” But Daniel said to the overseer whom the commander of the officials had appointed over Daniel, Hananiah, Mishael, and Azariah, “Please, test your servants for ten days, and let us be given some vegetables to eat and water to drink. Then let our appearance and the appearance of the young men who eat the king’s finest food be observed and compared by you, and deal with your servants in accordance with what you see.” So the man listened to them in this matter and tested them for ten days. At the end of ten days it seemed that they were looking better and healthier than all the young men who ate the king’s finest food. So the overseer continued to withhold their fine food and the wine they were to drink, and kept giving them vegetables. As for these four young men, God gave them knowledge and skill in all kinds of literature and wisdom; Daniel also understood all kinds of visions and dreams. [Luke 21:15; James 1:5-7] At the end of the time set by the king to bring all the young men in [before him], the commander of the officials presented them to Nebuchadnezzar. The king spoke with them, and among them all not one was found like Daniel, Hananiah, Mishael, and Azariah; so they were [selected and] assigned to stand before the king and enter his personal service. In every matter of wisdom and understanding about which the king consulted them, he found them ten times better than all the [learned] magicians and enchanters (Magi) in his whole realm. And Daniel remained there until the first year of [the reign of] King Cyrus [over Babylon; now this was at the end of the seventy-year exile of Judah (the Southern Kingdom) in Babylonia, as foretold by Jeremiah]. [Ezra 1:1-3; Jer 25:11, 12; 29:10]
