my King and my God, for Thy service be whatever useful thing my childhood learned; for Thy service, that I speak, write, read, reckon. For Thou didst grant me Thy discipline, while I was learning vanities; and my sin of delighting in those vanities Thou hast forgiven. In them, indeed, I learnt many a useful word, but these may as well be learned in things not vain; and that is the safe path for the steps of youth.
