The words of the wise prod us to live well.
They're like nails hammered home, holding life together.
They are given by God, the one Shepherd.
But regarding anything beyond this, dear friend, go easy. There's no end to the publishing of books, and constant study wears you out so you're no good for anything else. The last and final word is this:
Do what he tells you.
And that's it. Eventually God will bring everything that we do out into the open and judge it according to its hidden intent, whether it's good or evil.
