'Know' in the Bible

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.

I know that there is nothing better for them than to rejoice, and to do good as long as they live.

I know that whatever God does, it shall be forever. Nothing can be added to it, nor anything taken from it; and God has done it, that men should fear before him.

Better is a poor and wise youth than an old and foolish king who doesn't know how to receive admonition any more.

Guard your steps when you go to God's house; for to draw near to listen is better than to give the sacrifice of fools, for they don't know that they do evil.

I turned around, and my heart sought to know and to search out, and to seek wisdom and the scheme of things, and to know that wickedness is stupidity, and that foolishness is madness.

Whoever keeps the commandment shall not come to harm, and his wise heart will know the time and procedure.

For he doesn't know that which will be; for who can tell him how it will be?

Though a sinner commits crimes a hundred times, and lives long, yet surely I know that it will be better with those who fear God, who are reverent before him.

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

For all this I laid to my heart, even to explore all this: that the righteous, and the wise, and their works, are in the hand of God; whether it is love or hatred, man doesn't know it; all is before them.

For the living know that they will die, but the dead don't know anything, neither do they have any more a reward; for the memory of them is forgotten.

For man also doesn't know his time. As the fish that are taken in an evil net, and as the birds that are caught in the snare, even so are the sons of men snared in an evil time, when it falls suddenly on them.

A fool also multiplies words. Man doesn't know what will be; and that which will be after him, who can tell him?

The labor of fools wearies every one of them; for he doesn't know how to go to the city.

Give a portion to seven, yes, even to eight; for you don't know what evil will be on the earth.

As you don't know what is the way of the wind, nor how the bones grow in the womb of her who is with child; even so you don't know the work of God who does all.

In the morning sow your seed, and in the evening don't withhold your hand; for you don't know which will prosper, whether this or that, or whether they both will be equally good.

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