Christ a stumbling block & Rock of Offense

Ezekiel 14:7 - For every one of the house of Israel, or of the stranger that sojourneth in Israel, which separateth himself from me, and setteth up his idols in his heart, and putteth the stumblingblock of his iniquity before his face, and cometh to a prophet to enquire of him concerning me; I the LORD will answer him by myself:
1 Corinthians 1:23 - But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;
Romans 9:33 - As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.
