'Knoweth' in the Bible

And who knoweth whether he will be a wise man or a fool? yet shall he have rule over all my labour at which I have laboured, and wherein I have been wise under the sun. This also is vanity.

Who knoweth the spirit of the children of men? Doth it go upwards? and the spirit of the beasts, doth it go downwards to the earth?

Better is a poor but wise youth than an old and foolish king, who knoweth no more how to be admonished.

For what advantage hath the wise above the fool? what hath the poor, that knoweth to walk before the living?

For who knoweth what is good for man in life, all the days of his vain life which he spendeth as a shadow? for who can tell man what shall be after him under the sun?

For also thine own heart knoweth that oftentimes thou thyself likewise hast cursed others.

Who is as the wise? and who knoweth the explanation of things? A man's wisdom maketh his face to shine, and the boldness of his face is changed.

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

for he knoweth not that which shall be; for who can tell him how it shall be?

For all this I laid to my heart and indeed to investigate all this, that the righteous, and the wise, and their works, are in the hand of God; man knoweth neither love nor hatred: all is before them.

For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are taken with the snare, like them are the children of men snared in an evil time, when it falleth suddenly upon them.

And the fool multiplieth words: yet man knoweth not what shall be; and what shall be after him, who will tell him?
