Marrowy suggests one's most secret and innermost thoughts and tendencies, which can be discerned and brought to light only by Spirit through the spoken word (see Heb. 4:12). Marrowy also refers to the inner riches and substance upon which the soul may feed and be satisfied (Psalms 63:5); and abundant supply for the whole man (Isa. 25:6). To "fear Jehovah, and depart from evil" is "marrow to thy bones" (Prov. 3:7, 8; "refreshing, moistening," margin).
Mahavite, meaning live messenger, marrowy, preservation of life, living substance, signifies the enlightening idea of Spirit--man's all-sufficient life, inspiration, substance of supply--as entering into one's ruling love consciousness (Eliel the Mahavite was a warrior of David's, and David represents love as ruling in man).
