And I gave my heart to seek and search out by wisdom concerning all which is done under the heavens. It is a sad task God has given to the sons of men to be humbled by it.

Also every man to whom God has given riches and wealth, and has given him power to eat of it and to take his portion, and to rejoice in his labor; this is the gift of God.

Look on life with the wife whom you love all the days of the life of your vanity, which He has given you under the sun, all the days of your vanity. For that is your share in this life, and in your labor which you labor under the sun.

The words of the wise are like goads; yes, their collected words are like nails driven home; they are given from one Shepherd.
