Daniel 1:3-4

3Nebuchadnezzar had an officer who was called Ashpenaz. Ashpenaz had authority over the king's other officers. One day, Nebuchadnezzar said to Ashpenaz, ‘Bring some of the Israelite men to me. Choose some men from the king of Judah's family, and choose some men from the other important Israelite families.’

4Nebuchadnezzar wanted young men who were strong and handsome. They must be clever so that they could learn and understand things quickly. They must be good enough to become King Nebuchadnezzar's servants. They would learn the language of Babylon, and they would read its books.
