'Stumbling' in the Bible

but we preach Christ crucified, to the Jews a cause for stumbling, but to the Gentiles foolishness,

Only be careful that this liberty of yours [this power to choose] does not somehow become a stumbling block [that is, a temptation to sin] to the weak [in conscience].

Therefore, if food that I eat causes my brother to stumble, I will never eat meat again, in order to keep my brother from stumbling.

Give no occasion to stumbling, whether to Jews, or Greeks, or the assembly of God.
