Parashat Tzav, Why is fat to be offered by fire before God?


Vayikra / Leviticus 7:1 ‘Now this is the law of the guilt
offering; it is most holy. (NASB)
 In the Torah, the five major korbanot
(offerings) are described as being “most holy” as we see here in
Vayikra / Leviticus 7:1
and the detailing of the guilt offering. 
There are two major components of the guilt offering, (i) slaying of the animal taking its
blood and sprinkling it upon the altar (7:2)
and (ii) offering all its fat upon the altar, including the fat on the tail, the fat that
covers the entrails (7:3) and the fat that is
upon the kidneys and the liver.  It is interesting that in Hebrew the word for “fat”
is khelev meaning “fat, grease, fatness” whereas the Hebrew bible
uses kh-l-v “khelev” meaning “ tallow, fat, lard;” in addition to this,
the Hebrew root of khelev also means “milk.”  What is the significance of the
commandment to offer the fat upon the altar?  Why is the Hebrew word khelev used for “fat”
commanded to be offered upon the altar above the other types of meat in the body?  Could
it be that “fat” has a certain spiritual significance that is important for our lives?

Duane’s research expertise has focused upon functional materials development for the control, conversion, and release of process gases in Energy production technologies. His R&D interests include computational chemistry, developing novel technologies for converting biomass to fuels and studying their fundamental interactions during the chemical conversion process. His past experience includes sorbent development for pre- and post-combustion CO2 and SO2 capture, selective absorption of H2S from methane streams, O2 capture for oxy-fuel combustion, photocatalytic reduction of alcohols, NOx reduction catalysis, the development of oxygen carriers to combust fossil fuels (CH4 and coal) for the chemical looping combustion processes, and the extraction of rare earth elements using patent pending sorbents. His research expertise has focused on operando-characterization using Infrared, Raman, and UV-Vis spectroscopy to observe the nature of the catalytic active sites and reaction intermediates under realistic reaction conditions, allowing direct correlation of molecular/electronic structures with catalyst performance during Gas-Solid / Liquid-Solid Adsorption and Photocatalytic Processes with real time online analysis of reaction products using ICP-MS and mass spectrometry. His current work involves a multi-disciplinary approach to developing, understanding, and improving the catalytic gasification of coal and methane, high temperature chemical looping combustion, and the catalytic decomposition and gasification of biomass and coal using novel microwave reactor.​ He has been studying the Hebrew Scriptures and the Torah for 20+ years and sharing what he has learned.
