The Hebrew word for " #test " is "בֹּחֵן" (bochen).
This word carries the meaning of "examining, testing, or scrutinizing."
In the Hebrew context, it is often used to describe examining the kidneys and the heart, meaning to "test" or "search" them.
Here:
#Kidneys symbolize the deepest emotions or the innermost core of a person.
#Heart represents the mind, will, thoughts, and moral decisions, encompassing the entirety of a person's inner being.
Thus, the term "בֹּחֵן" (bochen) refers not to a superficial judgment but to God's ability to thoroughly penetrate and examine the deepest aspects of a person’s inner life.
