16I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.17And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.18For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
3I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what was that good for the sons of men, which they should do under the heaven all the days of their life.
12And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been already done.13Then I saw that wisdom excelleth folly, as far as light excelleth darkness.
26For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth 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.
11Wisdom is good with an inheritance: and by it there is profit to them that see the sun.12For wisdom is a defence, and money is a defence: but the excellency of knowledge is, that wisdom giveth life to them that have it.
15Now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man.16Then said I, Wisdom is better than strength: nevertheless the poor man's wisdom is despised, and his words are not heard.
