Romans 9:33 YLT

³¹  and Israel, pursuing a law of righteousness, at a law of righteousness did not arrive;

³²  wherefore? because -- not by faith, but as by works of law; for they did stumble at the stone of stumbling,

³³  according as it hath been written, 'Lo, I place in Sion a stone of stumbling and a rock of offence; and every one who is believing thereon shall not be ashamed.'
