Ecclesiastes 4:1-6:12

Everyone's toil is for their mouth, yet their appetite is never satisfied.

What advantage have the wise over fools?

What do the poor gain by knowing how to conduct themselves before others?

Better what the eye sees than the roving of the appetite.

This too is meaningless, a chasing after the wind.

Whatever exists has already been named, and what humanity is has been known;

no one can contend with someone who is stronger.

---

Whoever loves money never has enough;

whoever loves wealth is never satisfied with their income.

This too is meaningless.

As goods increase, so do those who consume them. 

And what benefit are they to the owners except to feast their eyes on them?

The sleep of a laborer is sweet, whether they eat little or much, but as for the rich, their abundance permits them no sleep.

I have seen a grievous evil under the sun.

The key to a strong friendship or a strong marriage is the third cord- what the other passages for today speak of as 'undivided devotion to the Lord' （1 Corinthians 7:35）and 'the fear of the Lord'(Proverbs 19:23a)
