TSK · Ecclesiastes 5:16

Don't turn aside; for [then you would go] after vain things which can't profit nor deliver, for they are vain.

What does man gain from all his labor in which he labors under the sun?

There is a grievous evil which I have seen under the sun: wealth kept by its owner to his harm.

The priests didn't say, 'Where is Yahweh?' and those who handle the law didn't know me. The rulers also transgressed against me, and the prophets prophesied by Baal, and walked after things that do not profit.

For what does it profit a man, to gain the whole world, and forfeit his life?
