Proverbs 3:28-30

New Catholic Bible

²⁸ Do not say to your neighbor,
    “Go away and come back again; I will repay you tomorrow,”
    when you can give him what is owed right then.
²⁹ Do not plot any evil against your neighbor
    who is living in peace beside you.
³⁰ Do not quarrel with someone without cause
    when that person has done you no harm.
