This is a proverb from the Book of Proverbs, which is the book of wisdom from the Bible, which was written by King Solomon, who prayed to God for understanding (and wisdom), which God did give him, because he asked. So, in essence, this is God's wisdom, just written through Solomon:

Start?children off on the way they should go,????and even when they are old they will not turn from it.

This is Proverbs 22:6, for more readings from Proverbs, buy a bible or visit Bible Gateway.
