Sirach 26:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ My child, keep sound the bloom of your youth,
    and do not give your strength to strangers.
²⁰ Seek a fertile field within the whole plain,
    and sow it with your own seed, trusting in your fine stock.
²¹ So your offspring will prosper,
    and, having confidence in their good descent, will grow great.
