'Know' in the Bible

I know that there is nothing good for them but to rejoice and to do well in their life;

I know that whatever God doeth, it shall be for ever; there is nothing to be added to it, nor anything to be taken from it; and God doeth it, that men should fear before him.

Keep thy foot when thou goest to the house of God, and draw near to hear, rather than to give the sacrifice of fools: for they know not that they do evil.

I turned, I and my heart, to know, and to search, and to seek out wisdom and reason, and to know wickedness to be folly, and foolishness to be madness;

Whoso keepeth the commandment shall know no evil thing; and a wise man's heart knoweth time and manner.

Though a sinner do evil a hundred times, and prolong his days, yet I know that it shall be well with them that fear God, because they fear before him;

When I applied my heart to know wisdom, and to see the business that is done upon the earth (for also there is that neither day nor night seeth sleep with his eyes),

then I saw that all is the work of God, and that man cannot find out the work that is done under the sun: because however man may labour to seek it out, yet doth he not find it; and even, if a wise man think to know it, he shall not be able to find it out.

For the living know that they shall die; but the dead know not anything, neither have they any more a reward, for the memory of them is forgotten.

The labour of fools wearieth them, because they know not how to go to the city.

Rejoice, young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thy heart, and in the sight of thine eyes; but know that for all these things God will bring thee into judgment.
