'Marrow' in the Bible
His breasts are full of milk, and his bones are moistened with marrow.
My soul shall be satisfied as with marrow and fatness; and my mouth shall praise thee with joyful lips:
It shall be health to thy navel, and marrow to thy bones.
And in this mountain shall the LORD of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined.
For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
