Sirach 7:18-20

Revised Standard Version Catholic Edition

¹⁸ Do not exchange a friend for money,
    or a real brother for the gold of Ophir.
¹⁹ Do not deprive yourself of a wise and good wife,
    for her charm is worth more than gold.
²⁰ Do not abuse a servant who performs his work faithfully,
    or a hired laborer who devotes himself to you.
