Hebrews 4:13

The LORD looketh from heaven; he beholdeth all the sons of men. From the place of his habitation he looketh upon all the inhabitants of the earth. He fashioneth their hearts alike; he considereth all their works.

Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.

The eyes of the LORD are in every place, beholding the evil and the good.

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.

For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.

For his eyes are upon the ways of man, and he seeth all his goings.

Hell is naked before him, and destruction hath no covering.

Thou hast set our iniquities before thee, our secret sins in the light of thy countenance.

And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.

Hell and destruction are before the LORD: how much more then the hearts of the children of men?

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. outward...: Heb. eyes

Shall not God search this out? for he knoweth the secrets of the heart.
