What does Daniel 1:19 mean?

After interviewing all the youths who completed the three-year training (Daniel 1:1–5), Nebuchadnezzar appointed Daniel, Hananiah, Mishael, and Azariah (Daniel 1:6–7) to prestigious positions in his court. Their refusal to partake of the king's food and wine while they followed a diet approved by Levitical law honored the God of Israel. Despite enormous pressure to conform to Babylonian culture, they remained true to their Hebrew convictions. Although they were far from home and the temple, they remained devoted to God and His Word. Neither political pressure nor peer pressure caused them to dishonor God.

Proverbs 22:29 states, "Do you see a man skillful in his work? He will stand before kings." Though all four had been given Babylonian names, as well, they are labeled here with their original Hebrew names. This is meant to emphasize that their God, the God of Israel, had worked in their lives to advance them to prominent positions.
