Philippians 2:30 describes Epaphroditus risking his life to serve Paul—another example of the Philippians' support for Paul, complementing their prayers mentioned in 1:19.

Romans 8:28 provides the theological principle that God works all things for good, supporting Paul's confidence in deliverance here.

2 Corinthians 1:11 directly parallels — prayers of others bring deliverance and thanksgiving, exactly the dynamic Paul describes here.

Philemon 1:22 echoes the same hope: Paul expects to be restored through the prayers of the saints, closely matching the deliverance theme in Philippians 1:19.
