Sirach 30:21-23

Revised Standard Version

²¹ Do not give yourself over to sorrow,
    and do not afflict yourself deliberately.
²² Gladness of heart is the life of man,
    and the rejoicing of a man is length of days.
²³ Delight your soul and comfort your heart,
    and remove sorrow far from you,
for sorrow has destroyed many,
    and there is no profit in it.
