Ecclesiastes 12:10

and the dust returns to the earth as it was,

and the spirit returns to God who gave it.

“Vanity of vanities,” says the Preacher.

“All is vanity!”

Further, because the Preacher was wise, he still taught the people knowledge. Yes, he pondered, sought out, and set in order many proverbs.

The words of the wise are like goads; and like nails well fastened are words from the masters of assemblies, which are given from one shepherd.

Furthermore, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

This is the end of the matter. All has been heard. Fear God and keep his commandments; for this is the whole duty of man.
