Concise Bible Dictionary:

Both in the Hebrew and in the Greek the words signify “knowledge,” and are generally so translated. They are rendered “science” only in Daniel 1:44Children in whom was no blemish, but well favored, and skilful in all wisdom, and cunning in knowledge, and understanding science, and such as had ability in them to stand in the king's palace, and whom they might teach the learning and the tongue of the Chaldeans. (Daniel 1:4), where “knowledge” and “wisdom” are also mentioned; and in 1 Timothy 6:2020O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called: (1 Timothy 6:20), where it is science, or knowledge, “falsely so called,” doubtless alluding in Daniel to the speculations of the Magi, and in the Epistle to Timothy to the philosophers or Gnostic heretics, whose “knowledge” had no real foundation.
