Philippians 1:3-6
3 I thank my God whenever I remember you, 4 always in every request of mine on behalf of you all making my requests with joy, 5 for your partnership in furtherance of the gospel from the first day until now; 6 being confident of this very thing, that he who began a good work in you will complete it until the day of Jesus Christ.
Philippians 4:15
15 You yourselves also know, you Philippians, that in the beginning of the gospel, when I departed from Macedonia, no assembly shared with me in the matter of giving and receiving but you only.
