If we took the first thirteen verses of Ecclesiastes 7 on their own, we might initially think
they belong in the book of Proverbs. They are fairly standard Hebrew proverbial
couplets (with the occasional interjection).
This is not the first time the form is used in Ecclesiastes. There are a few couplets sprinkled
through chapters 1, 4 and 5, and we will encounter more in chapters 8,
10 and 11.
What is different about the proverbs we find in Ecclesiastes in that they do not skip around from
subject to subject with anything like their usual apparent randomness, but
instead serve the book’s larger treatise. They are thematically linked to one
another, to what comes before them, and to what follows them.
