Proverbs 3:28-30

New Revised Standard Version Catholic Edition

²⁸ Do not say to your neighbor, “Go, and come again,
    tomorrow I will give it”—when you have it with you.
²⁹ Do not plan harm against your neighbor
    who lives trustingly beside you.
³⁰ Do not quarrel with anyone without cause,
    when no harm has been done to you.
