Seeing there be many things that increase vanity
As appears by all that has been said in this and the preceding chapters; such as wisdom and knowledge, wealth and riches, pleasure, power, and authority. Man is a poor vain creature himself, all he is and has is vanity; and these serve but to increase it, and make him vainer and vainer still; what [is] man the better?
for these things? not at all, rather the worse, being more vain; there is no profit by them, no excellency arises to him from them, no happiness in them, nothing that will be of any service to him, especially with respect to a future state, or when he comes to die. It may be rendered, as it is in the Septuagint and Vulgate Latin versions, "seeing there are many words that multiply vanity"; as all such words do that are used with God by way of murmur and complaint concerning a man's lot and condition in this world, and as expostulating and contending with him about it; these increase sin, and by them men contract more guilt, and therefore are not the better for such litigations, but the worse; and so the words stand in connection with ( Ecclesiastes 6:10 ) : but the former sense seems best, this being the conclusion of the wise man's discourse concerning vanity. So the Targum and Jarchi understand it of things, and not words.
