Not Medical Advice: In our human body, 'reins' are also known as our 'kidneys' or the region of the kidneys, or the lower part of the back.
In the first vernacular versions of the Bible in English, the translators elected to use the term "reins" instead of kidneys in differentiating the metaphoric uses of human kidneys from that of their mention as anatomic organs of sacrificial animals burned at the altar.
As per Jasn.asnjournals.org, the kidneys are mentioned five times in the Bible as the organs examined by God to pass judgment on a person. They are mentioned either before or after but always in parallel with the heart, as for example, “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” (Jer. 17:10), and, “Examine me, O Lord, and prove me; try my reins and my heart” (Psalms 26:2).
In health news, a new study has found that using incompatible kidneys in transplants is better than doing no transplant at all. Doctors from the New England Journal of Medicine successfully altered patients’ immune systems to allow them to accept kidneys from incompatible donors. Find out more at New York Times.
