Luz (bone)
The word luz in Hebrew (Hebrew: 'לוז') means nut or almond.[1] Because of this it became associated with the small bone at the top of the spinal column (the first cervical vertebra, C1 or the Atlas), underneath the brain, on the top of the spine, (the bone where the knot of the tefillin rests). It is about the size of a kernel of barley. The Zohar states that the luz is the bone in the spine that appears like the head of a snake,[2] implying that is the sacrum, because the sacrum is the only bone in the spine that looks like the head of a snake. The sacrum has similar significance to the luz as a source of resurrection in Egyptian and Greek cultures contemporary to the Zohar and Talmud.[3][4] The sacrum has a pattern of dimples and shape that appear similar to those of the almond shell.
Jewish traditions teach that this is the bone from which the body will be rebuilt at the time of resurrection, and share the idea that this bone does not decay.[5] There is an aggadah (legend) in the midrash that the Roman Emperor Hadrian asked how man would be revived in the world to come, and Rabbi Joshua Ben Hananiah replied that it would be "From Luz, in the back-bone." "Prove this to me," said Hadrian. Then the Rabbi took Luz, a small bone of the spine, and immersed it in water, but it was not softened; he put it into the fire, but it was not consumed; he put it into a mill, but it could not be pounded; he placed it upon an anvil and struck it with a hammer, but the anvil split and the hammer was broken. (Ecclesiastes Rabbah xii / Genesis Rabbah xviii).
Biblical
The luz bone narrative can be linked directly to the human-divine encounter in Ezekiel 37 which alludes to the time of the return of the Jewish People to their land after a long exile. The valley of dry bones, that is, the exile or in a metaphorical sense, human constituent, encounters the immortal spirit of God in Eretz Israel, the land of the living, in contrast to this valley.
