And who of men knoweth, what things be of man, but the spirit of man that is in him? So what things be of God, no man knoweth, but the Spirit of God.
Whether thou hast heard the counsel of God, and whether his wisdom is lower than thou?
The heart that knoweth the bitter-ness of his soul; a stranger shall not be meddled [or mingled] in the joy thereof.
The lantern of the Lord is the spirit of man, that seeketh out all the privates of the womb.
As deep water, so counsel is in the heart of a man; but a wise man shall draw it out.
The heart of man is shrewd, and unsearchable; who shall know it?
And the word of wisdom is given to one by Spirit; to another the word of knowing, by the same Spirit;
but God showed to us by his Spirit. For why the Spirit searcheth all things, yea, the deep things of God.
