'Welfare' in the Bible

for I know [with confidence] that this will turn out for my deliverance and spiritual well-being, through your prayers and the [superabundant] supply of the Spirit of Jesus Christ [which upholds me].

I do not have anyone else like him who takes a genuine interest in your welfare.

I rejoiced greatly in the Lord, that now at last you have renewed your concern for me; indeed, you were concerned about me before, but you had no opportunity to show it.
