Verse 1
To be left at Athens. It would seem from 1 Thessalonians 3:1-8, that Timothy came to Paul at Athens, as Paul had directed, (Acts 17:15,) and that Paul sent him back from that city to Thessalonica for the purposes mentioned in 1 Thessalonians 3:2 of this chapter. His returning to Paul again, as mentioned in 1 Thessalonians 3:6, was probably at Corinth, as stated Acts 18:5.

Verse 5
I sent; referring to the mission of Timothy alluded to above.

Verse 10
Night and day; very frequently and earnestly.

Verse 11
Direct our way unto you, open the way for us to visit you at such a time as shall be in accordance with the divine will.
