'Knowledge' in the Bible

I communed with mine own heart, saying, Lo, I have gotten me great wisdom above all that were before me in Jerusalem; yea, my heart hath had great experience of wisdom and knowledge.

For in much wisdom is much grief; and he that increaseth knowledge increaseth sorrow.

For there is a man whose labor is with wisdom, and with knowledge, and with skilfulness; yet to a man that hath not labored therein shall he leave it for his portion. This also is vanity and a great evil.

For to the man that pleaseth him God giveth 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 pleaseth God. This also is vanity and a striving after wind.

For wisdom is a defence, even as money is a defence; but the excellency of knowledge is, that wisdom preserveth the life of him that hath it.

Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, whither thou goest.

And further, because the Preacher was wise, he still taught the people knowledge; yea, he pondered, and sought out, and'set in order many proverbs.
