Proverbs

Every way of a man is right in his own eyes: but the Lord pondereth the hearts.

But the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.

And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.

There is a generation that are pure in their own eyes, and yet is not washed from their filthiness.

I the Lord search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
