'Lads' in the Bible

lads in whom there is no blemish, and of good appearance, and skilful in all wisdom, and possessing knowledge, and teaching thought, and who have ability to stand in the palace of the king, and to teach them the literature and language of the Chaldeans.

and the chief of the eunuchs saith to Daniel, 'I am fearing my lord the king, who hath appointed your food and your drink, for why doth he see your faces sadder than those of the lads which are of your circle? then ye have made my head indebted to the king,'

and our appearance is seen before thee, and the appearance of the lads who are eating the king's portion of food, and as thou seest -- deal with thy servants.'

and at the end of ten days their appearance hath appeared better and fatter in flesh then any of the lads who are eating the king's portion of food.

As to these four lads, God hath given to them knowledge and understanding in every kind of literature, and wisdom; and Daniel hath given instruction about every kind of vision and dreams.
