Sirach 26:20-22

New Revised Standard Version, Anglicised Catholic Edition

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.
²² A prostitute is regarded as spittle,
    and a married woman as a tower of death to her lovers.
