LEB(i)
18 So I hated all my toil with which I have toiled under the sun, for I must leave it behind to someone who will be after me.
19 And who knows whether he will be wise or foolish? Yet he will exercise control of all the fruit of my toil with which I toiled wisely under the sun. This also is vanity!
20 So ⌊I began to despair⌋* of all the toil with which I toiled under the sun.
21 For although a person may toil with great wisdom and skill, he must leave his reward to someone who has not toiled for it. This also is vanity and a great calamity.
