Romans
Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone;
As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.
Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.
1 Corinthians
But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak.
1 Peter
And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
