DAN 1:4

4 Yeladim in whom was no blemish, but well-favored, and skillful in all chochmah [(wisdom)], and cunning in da'as [(knowledge)], and understanding science, and such as had ability in them to stand in the heikhal hamelech [(kingʼs palace)], and whom they might teach the sefer and lashon of the Kasdim [(Chaldeans)].
