'Young' in the Bible

And Jesus, when he had found a young ass, sat thereon; as it is written,

Have no fear, daughter of Zion: see your King is coming, seated on a young ass.

The young woman at the gate asked Peter, "You aren't one of this man's disciples, too, are you?" "I am not," he replied.

Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.
