John Lightfoot on John 11:25

[I am the resurrection.] Be it so, O Jew (if you will, or it can be), that the little bone luz, in the backbone, is the seed and principle of your resurrection: as to us, our blessed Jesus, who hath raised himself from the dead, is the spring and principle of ours.

"Hadrian (whose bones may they be ground, and his name blotted out!) asked R. Joshua Ben Hananiah, 'How doth a man revive again in the world to come?' He answered and said, 'From luz in the backbone.' Saith he to him, 'Demonstrate this to me.' Then he took luz, a little bone out of the backbone, and put it in water, and it was not steeped: he put it into the fire, and it was not burnt: he brought it to the mill, and that could not grind it: he laid it on the anvil, and knocked it with a hammer, but the anvil was cleft, and the hammer broken," &c. Why do ye not maul the Sadducees with this argument?
