19 And who knows whether he will be wise or a fool? Yet he will rule over all my labor in which I toiled and in which I have shown myself wise under the sun. This also is vanity.
20 Therefore I turned my heart and despaired of all the labor in which I had toiled under the sun.
21 For there is a man whose labor is with wisdom, knowledge, and skill; yet he must leave his heritage to a man who has not labored for it. This also is vanity and a great evil.
22 For what has man for all his labor, and for the striving of his heart with which he has toiled under the sun?
23 For all his days are sorrowful, and his work burdensome; even in the night his heart takes no rest. This also is vanity.
24 Nothing is better for a man than that he should eat and drink, and that his soul should enjoy good in his labor. This also, I saw, was from the hand of God.
25 For who can eat, or who can have enjoyment, more than I?
26 For God gives wisdom and knowledge and joy to a man who is good in His sight; but to the sinner He gives the work of gathering and collecting, that he may give to him who is good before God. This also is vanity and grasping for the wind.

Almeida Atualizada (Portuguese) AA

Eclesiastes 2:19 E quem sabe se será sábio ou estulto? Contudo, ele se assenhoreará de todo o meu trabalho em que me afadiguei, e em que me houve sabiamente debaixo do sol; também isso é vaidade.

English Standard Version ESV

Ecclesiastes 2:19 and who knows whether he will be wise or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity.

King James Version KJV

Ecclesiastes 2:19 And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.

Nova Versão Internacional NVIP

Eclesiastes 2:19 E quem pode dizer se ele será sábio ou tolo? Todavia, terá domínio sobre tudo o que realizei com o meu trabalho e com a minha sabedoria debaixo do sol. Isso também não faz sentido.
