30 ²¹ Do not give yourself over to sorrow,
and do not afflict yourself deliberately.
30 ²² Gladness of heart is the life of man,
and the rejoicing of a man is length of days.
30 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.
30 ²⁴ Jealousy and anger shorten life,
and anxiety brings on old age too soon.
30 ²⁵ A man of cheerful and good heart
will give heed to the food he eats.
