As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.

And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:

And why? Simply because Israel has relied not on faith but on what they could do. They have stumbled over the stone that makes men stumble ??33 as it is written, Here I lay a stone in Sion that will make men stumble, even a rock to trip them up; but he who believes in Him will never be disappointed.
