According to Philippians 4:16, in which city did the Philippians provide for Paul's needs again and again?

Answer: Thessalonica

No church but the Philippians shared with Paul in giving; even in Thessalonica they provided for his needs again and again.

“And as you Philippians know, in the early days of the gospel, when I left Macedonia, no church but you partnered with me in the matter of giving and receiving. For even while I was in Thessalonica, you provided for my needs again and again.”— Philippians 4:15-16 (BSB)
