'Marrow' in the Bible

His buckets are filled with milk, his bone marrow is healthy.

"On this mountain, the LORD of the Heavenly Armies will prepare for all nations a banquet of rich food, a banquet of well-aged wines rich food full of marrow, and refined wines of the finest vintage

For the word of God is living and active, sharper than any double-edged sword, piercing until it divides soul and spirit, joints and marrow, as it judges the thoughts and purposes of the heart.
