Daniel 1:17 KJV

15And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king’s meat.

16Thus Melzar took away the portion of their meat, and the wine that they should drink; and gave them pulse.

17As for these four children, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams.

18Now at the end of the days that the king had said he should bring them in, then the prince of the eunuchs brought them in before Nebuchadnezzar.

19And the king communed with them; and among them all was found none like Daniel, Hananiah, Mishael, and Azariah: therefore stood they before the king.
