When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much he had learned in seven years. – Mark Twain

Hear, O sons, a father’s instruction, and be attentive, that you may gain insight, for I give you good precepts; do not forsake my teaching…Let your heart hold fast my words; keep my commandments, and live. Get wisdom; get insight; do not forget, and do not turn away from the words of my mouth. … Hear, my son, and accept my words, that the years of your life may be many. I have taught you the way of wisdom; I have led you in the paths of uprightness. (Proverbs 4.1 – 5, 10, 11, ESV)
