'Pupil' in the Bible

“He found him in a desert land,And in the howling waste of a wilderness;He encircled him, He cared for him,He guarded him as the pupil of His eye.

They cast lots for their duties, all alike, the small as well as the great, the teacher as well as the pupil.

A pupil is not above his teacher; but everyone, after he has been fully trained, will be like his teacher.
