7:9Oh let the wickedness of the wicked come to an end; but establish the just: for the righteous God trieth the hearts and reins.

16:7I will bless the LORD, who hath given me counsel: my reins also instruct me in the night seasons.

26:2Examine me, O LORD, and prove me; try my reins and my heart.

139:13For thou hast possessed my reins: thou hast covered me in my mother's womb.
