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.
For you even sent to Thessalonica, once, and then a second time, for what was useful to me.
For unto Thessalonica also you sent once and again for my use.
