'Knows' in the Bible

For who among men knows the thoughts of a man except the spirit of the man that is in him? In the same way, no one knows the thoughts of God except the Spirit of God.

and again, The Lord knows that the reasonings of the wise are meaningless.

If anyone thinks he knows anything, he does not yet know it as he ought to know it.

Love is patient and kind. Love knows neither envy nor jealousy. Love is not forward and self-assertive, nor boastful and conceited.

She knows how to be silent. She is full of trust, full of hope, full of patient endurance.

If anyone does not recognize this [that it is a command of the Lord], he is not recognized [by God].
