'Marrow' in the Bible

His pails are full of milk [his sides are filled out with fat],And the marrow of his bones is moist,

My soul [my life, my very self] is satisfied as with marrow and fatness,And my mouth offers praises [to You] with joyful lips.

It will be health to your body [your marrow, your nerves, your sinews, your muscles—all your inner parts]And refreshment (physical well-being) to your bones.

On this mountain [Zion] the Lord of hosts will prepare a lavish banquet for all peoples [to welcome His reign on earth],A banquet of aged wines—choice pieces [flavored] with marrow,Of refined, aged wines.

For the word of God is living and active and full of power [making it operative, energizing, and effective]. It is sharper than any two-edged sword, penetrating as far as the division of the soul and spirit [the completeness of a person], and of both joints and marrow [the deepest parts of our nature], exposing and judging the very thoughts and intentions of the heart.
