'Reins' in the Bible

His arrows encompass me round about, he cleaveth my reins asunder and doth not spare; he poureth out my gall upon the ground.

Whom I shall see for myself, and mine eyes shall behold, and not another: my reins are consumed within me.

Oh let the wrong of the wicked come to an end, and establish thou the righteous man; even thou that triest the hearts and reins, the righteous God.

I will bless Jehovah, who giveth me counsel; even in the nights my reins instruct me.

Prove me, Jehovah, and test me; try my reins and my heart:

When my heart was in a ferment, and I was pricked in my reins,

For thou hast possessed my reins; thou didst cover me in my mother's womb.

and my reins shall exult, when thy lips speak right things.

And righteousness shall be the girdle of his reins, and faithfulness the girdle of his loins.

But thou, Jehovah of hosts, who judgest righteously, who triest the reins and the heart, let me see thy vengeance on them: for unto thee have I revealed my cause.

Thou hast planted them, they also have taken root: they advance, yea, they bring forth fruit: thou art near in their mouth, but far from their reins.

I Jehovah search the heart, I try the reins, even to give each one according to his ways, according to the fruit of his doings.

And thou, Jehovah of hosts, who triest the righteous, who seest the reins and the heart, let me see thy vengeance on them; for unto thee have I revealed my cause.

He hath caused the arrows of his quiver to enter into my reins.

and her children will I kill with death; and all the assemblies shall know that I am he that searches the reins and the hearts; and I will give to you each according to your works.
