Jeremiah

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.

Search me, O God, and know my heart: try me, and know my thoughts:

And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the Lord searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.

Oh let the wickedness of the wicked come to an end; but establish the just: for the righteous God trieth the hearts and reins.

But, O Lord of hosts, that triest the righteous, and seest the reins and the heart, let me see thy vengeance on them: for unto thee have I opened my cause.
