Why? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumbling stone;

As it is written, Behold, I lay in Zion a stumbling stone and rock of offense: and whosoever believes on him shall not be ashamed.

And he shall be as a sanctuary; but a stone of stumbling and a rock of offense to both the houses of Israel, for a trap and for a snare to the inhabitants of Jerusalem.

And, A stone of stumbling, and a rock of offense, even to them who stumble at the word, being disobedient: to which also they were appointed.
