“He shall remove the entire tail from above the advice [kidneys]”
~ Leviticus 3:9

The book of Leviticus deals with the sacrifices offered in the Temple, in all their gory details.

Clearly the verse refers to “kidneys” – so why write the word “advice”?

Because kidneys perform an essential function, their location is buried beneath the ribcage, concealed by other organs and enclosed by layers of thick fat, tough membranes and lymph-nodes. So too our innermost thoughts and deepest desires are hidden from our conscious mind.

Beware, much of what ‘advises’ you is totally invisible.
