Indeed, even while I was still in Thessalonica, you sent more than once to relieve my wants.
For even in Thessalonica ye sent once and again unto my necessity.
For even in Thessalonica you sent [me contributions] for my needs, not only once but a second time.
for even in Thessalonica ye sent once and again unto my need.
You sent contributions repeatedly to take care of my needs even while I was in Thessalonica.
For you even sent to Thessalonica, once, and then a second time, for what was useful to me.
