These 4 "children"

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.

Prove thy servants,

 I beseech thee,

ten days;

and let them give us pulse to eat,

and water to drink.

Thus Melzar took away the portion of their meat, a

nd the wine that they should drink;

and gave them pulse.

As for these four children,

God gave them knowledge and skill in all learning and wisdom:

and Daniel had understanding in all visions and dreams.

Daniel 1:8,12,16,17
