'Know' in the Bible

And I set my mind to know wisdom and to know madness and folly; I realized that this also is striving after wind.

The wise man’s eyes are in his head, but the fool walks in darkness. And yet I know that one fate befalls them both.

I know that there is nothing better for them than to rejoice and to do good in one’s lifetime;

I know that everything God does will remain forever; there is nothing to add to it and there is nothing to take from it, for God has so worked that men should fear Him.

Guard your steps as you go to the house of God and draw near to listen rather than to offer the sacrifice of fools; for they do not know they are doing evil.

I directed my mind to know, to investigate and to seek wisdom and an explanation, and to know the evil of folly and the foolishness of madness.

Although a sinner does evil a hundred times and may lengthen his life, still I know that it will be well for those who fear God, who fear Him openly.

When I gave my heart to know wisdom and to see the task which has been done on the earth (even though one should never sleep day or night),

and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, “I know,” he cannot discover.

For I have taken all this to my heart and explain it that righteous men, wise men, and their deeds are in the hand of God. Man does not know whether it will be love or hatred; anything awaits him.

For the living know they will die; but the dead do not know anything, nor have they any longer a reward, for their memory is forgotten.

Moreover, man does not know his time: like fish caught in a treacherous net and birds trapped in a snare, so the sons of men are ensnared at an evil time when it suddenly falls on them.

The toil of a fool so wearies him that he does not even know how to go to a city.
