(מֹחִ , mo'ach, fatness, Job 21:24; kindred is the verb מָחָה, machah', Isaiah 25:6, "fatness unmarrowed," i.e. drawn out from the marrow- bones, and therefore the most delicate; μυελός, Hebrews 4:12), the soft, oleaginous substance contained in the hollow of the bones of animals (Job 21:23); used figuratively for the delicate and most satisfying provisions of the Gospel (Isaiah 25:6), and likewise in the New Testament for the most secret thoughts of the heart (Hebrews 4:12). Other terms so rendered are חֵלֶב (che'leb, Psalms 63:5, fat or fatness, as elsewhere rendered) and שַׁקּוּי(shikku'y, Proverbs 3:8, a moistening, i.e. refreshing of the bones; or "drink," as in Hosea 2:5).
