'Knoweth' in the Bible

So that she findeth not the level path of life: Her ways are unstable, and'she knoweth it not.

Till an arrow strike through his liver; As a bird hasteth to the snare, And knoweth not that it is for his life.

The foolish woman is clamorous;'she is'simple, and knoweth nothing.

But he knoweth not that the dead are there; That her guests are in the depths of Sheol.

The heart knoweth its own bitterness; And a stranger doth not intermeddle with its joy.

For their calamity shall rise suddenly; And the destruction from them both, who knoweth it?

he that hath an evil eye hasteth after riches, And knoweth not that want shall come upon him.
