'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.
