'Childhood' in the Bible

If you pamper a servant from his childhood, later on he'll become ungrateful.

Banish sorrow from your heart, and evil from your body, since both childhood and the prime of life are pointless.

"But stand up now with your spells and your many incantations, at which you have labored from your childhood until today,

So will they be to you those with whom you toiled and did business since your childhood they wander about, each in his own direction; there is not one who can save you.
