I said in my heart, “I have acquired great wisdom, surpassing all who were over Jerusalem before me, and my heart has had great experience of wisdom and knowledge.”

For in much wisdom is much vexation, and he who increases knowledge increases sorrow.

because sometimes a person who has toiled with wisdom and knowledge and skill must leave everything to be enjoyed by someone who did not toil for it. This also is vanity and a great evil.

For to the one who pleases him God has given wisdom and knowledge and joy, but to the sinner he has given the business of gathering and collecting, only to give to one who pleases God. This also is vanity and a striving after wind.

For the protection of wisdom is like the protection of money, and the advantage of knowledge is that wisdom preserves the life of him who has it.

Whatever your hand finds to do, do it with your might, for there is no work or thought or knowledge or wisdom in Sheol, to which you are going.

Wisdom Better Than Folly

Again I saw that under the sun the race is not to the swift, nor the battle to the strong, nor bread to the wise, nor riches to the intelligent, nor favor to those with knowledge, but time and chance happen to them all.

Fear God and Keep His Commandments

Besides being wise, the Preacher also taught the people knowledge, weighing and studying and arranging many proverbs with great care.
