Why? Because they sought it not from faith, but as it were from works: they stumbled over the stone of stumbling,

as has been written, Behold, I lay in Zion a stone of stumbling and a rock of offence: and he that believeth on him shall not be ashamed.

Then I say; Whether did they stumble that they may fall? it could not be so: but by their fall, salvation came to the Gentiles, in order to provoke them to jealousy.

it is good neither to eat flesh, nor to drink wine, nor anything by which your brother stumbles.
