'Knoweth' in the Bible

And who knoweth whether he is wise or foolish? yet he doth rule over all my labour that I have laboured at, and that I have done wisely under the sun! this also is vanity.

Who knoweth the spirit of the sons of man that is going up on high, and the spirit of the beast that is going down below to the earth?

For what advantage is to the wise above the fool? What to the poor who knoweth to walk before the living?

For who knoweth what is good for a man in life, the number of the days of the life of his vanity, and he maketh them as a shadow? for who declareth to man what is after him under the sun?

Who is as the wise? and who knoweth the interpretation of a thing? The wisdom of man causeth his face to shine, and the hardness of his face is changed.

Whoso is keeping a command knoweth no evil thing, and time and judgment the heart of the wise knoweth.

For he knoweth not that which shall be, for when it shall be who declareth to him?

For even man knoweth not his time; as fish that are taken hold of by an evil net, and as birds that are taken hold of by a snare, like these are the sons of man snared at an evil time, when it falleth upon them suddenly.

And the fool multiplieth words: 'Man knoweth not that which is, And that which is after him, who doth declare to him?'
