1 Corinthians 8:11

9 Be careful, however, that your freedom does not become a stumbling block to the weak.

10 For if someone with a weak conscience sees you who are well informed eating in an idol’s temple, will he not be encouraged to eat food sacrificed to idols?

So this weak brother, for whom Christ died, is destroyed by your knowledge.

12 By sinning against your brothers in this way and wounding their weak conscience, you sin against Christ.

13 Therefore, if what I eat causes my brother to stumble, I will never eat meat again, so that I will not cause him to stumble.

Do read the surrounding verses too, because the context often says more than a single verse.
