From men which are your hand, O LORD, from men of the world, which have their portion in this life, and whose belly you fill with your hid treasure: they are full of children, and leave the rest of their substance to their babes.
And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail has God given to the sons of man to be exercised therewith.
Then I looked on all the works that my hands had worked, and on the labor that I had labored to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
For there is a man whose labor is in wisdom, and in knowledge, and in equity; yet to a man that has not labored therein shall he leave it for his portion. This also is vanity and a great evil.
For God gives to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he gives travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
Why I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion: for who shall bring him to see what shall be after him?
Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labor that he takes under the sun all the days of his life, which God gives him: for it is his portion.
Live joyfully 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 portion in this life, and in your labor which you take under the sun.
According to the grace of God which is given to me, as a wise master builder, I have laid the foundation, and another builds thereon. But let every man take heed how he builds thereupon.
