Ecclesiastes 2:7-8

2:7 I purchased male and female slaves,

and I owned slaves who were born in my house;

I also possessed more livestock – both herds and flocks –

than any of my predecessors in Jerusalem.

2:8 I also amassed silver and gold for myself,

as well as valuable treasures taken from kingdoms and provinces.

I acquired male singers and female singers for myself,

and what gives a man sensual delight – a harem of beautiful concubines!

Ecclesiastes 3:18

3:18 I also thought to myself, “It is for the sake of people,

so God can clearly show them that they are like animals.

3:21 Who really knows if the human spirit ascends upward,

and the animal’s spirit descends into the earth?

8:11 When a sentence is not executed at once against a crime,

the human heart is encouraged to do evil.

Concluding Exhortation: Fear God and Obey His Commands!

12:12 Be warned, my son, of anything in addition to them.

There is no end to the making of many books,

and much study is exhausting to the body.
