'Marrow' in the Bible

His pails are full of milk. The marrow of his bones is moistened.

In this mountain, Yahweh of Armies will make all peoples a feast of fat things, a feast of choice wines, of fat things full of marrow, of well refined choice wines.

For the word of God is living, and active, and sharper than any two-edged sword, and piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.
