Ben Sira 30:23

23 The joyfulness of the heart, is the life of a man, and a never failing treasure of holiness: and the joy of a man is length of life.

Ben Sira 30:23 In-Context

21 He seeth with his eyes, and groaneth, as an eunuch embracing a virgin, and sighing.

22 Give not up thy soul to sadness, and afflict not thyself in thy own counsel.

23 The joyfulness of the heart, is the life of a man, and a never failing treasure of holiness: and the joy of a man is length of life.

24 Have pity on thy own soul, pleasing God, and contain thyself: gather up thy heart in his holiness: and drive away sadness far from thee.

25 For sadness hath killed many, and there is no profit in it.
