Wisdom of Ben Sira 32:3-5

New Catholic Bible

³ As you grow older, you may speak, for you are entitled to do so,
    but do not flaunt your knowledge and do not interrupt the music.
⁴ When there is entertainment, do not pour out a stream of talk;
    such is the wrong time to display your wisdom.
⁵ Like a jewel in a setting of gold
    is a concert of music at which wine is served.
