'Young' in the Bible

to give prudence to the simple, knowledge and discretion to the young man:

I saw among the simple ones. I discerned among the youths a young man void of understanding,

The glory of young men is their strength. The splendor of old men is their gray hair.

"The eye that mocks at his father, and scorns obedience to his mother: the ravens of the valley shall pick it out, the young eagles shall eat it.
