G'day and Shalom,
I was asked the following question, “what do Kidneys represented in the Hebrew Bible?”. Michael who is a medical student, asked an interesting question, that will help all of us to understand the Bible better. So here is a detailed answer from the scriptures. I hope it satisfies your curiosity as it did his (and mine).
Thanks for the question and Blessings in Yeshua Adon Olam Paul
