Daniel 1:7 (KJV)

And the king appointed them a daily provision of the king’s meat, and of the wine which he drank: so nourishing them three years, that at the end thereof they might stand before the king.

Now among these were of the children of Judah, Daniel, Hananiah, Mishael, and Azariah:

Unto whom the prince of the eunuchs gave names: for he gave unto Daniel the name of Belteshazzar; and to Hananiah, of Shadrach; and to Mishael, of Meshach; and to Azariah, of Abed–nego.

But Daniel purposed in his heart that he would not defile himself with the portion of the king’s meat, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.

Now God had brought Daniel into favour and tender love with the prince of the eunuchs.
