Wisdom of Ben Sira 21:20-22

New Catholic Bible

²⁰ A fool laughs at the top of his voice,
    but a prudent man smiles quietly.
²¹ Like an ornament of gold is instruction to a sensible man,
    like a bracelet on his right arm.
²² A fool steps boldly into a house,
    whereas the well-bred person waits outside respectfully.
