1 Corinthians 8:13 answers the question in 8:11 by resolving to never cause stumbling — Paul's practical conclusion.

In 1 Corinthians 10:33, Paul applies the same principle: seeking others' salvation rather than one's own advantage, directly following the warning about destroying a weak brother.

Romans 14:15 uses near-identical language: 'Do not destroy the one for whom Christ died' when your eating grieves a brother.

Romans 14:20 warns not to 'destroy the work of God' for food, echoing the warning against causing a weak brother to perish in 1 Corinthians 8:11.

Romans 14:21 applies the same principle: avoid anything that causes your brother to stumble, directly extending the concern for the weak.

Romans 15:1-3 grounds the duty not to please oneself in Christ's example, reinforcing the call to protect the weak brother from perishing.

Ezekiel 13:19 condemns false prophets who 'put to death souls who should not die,' akin to destroying a weak brother for whom Christ died.

In Matthew 18:14, God's will that no little one perish echoes Paul's warning — the weak brother is equally precious.

Luke 17:2 issues the same severe warning against causing a little one to stumble, reinforcing the gravity of destroying the weak brother.

Romans 14:3 commands not despising the weak — directly addressing the same food issue Paul warns about here.

Nehemiah 5:8 rebukes the exploitation of fellow Jews, paralleling the sin of harming a brother who is bought by Christ in 1 Corinthians 8:11.
