1 Thessalonians 2:9

2:9 For you recall, brothers and sisters, ¹  our toil and drudgery: By working night and day so as not to impose a burden on any of you, we preached to you the gospel of God.

1 Thessalonians 4:15

4:15 For we tell you this by the word of the Lord, ²  that we who are alive, who are left until the coming of the Lord, will surely not go ahead of those who have fallen asleep.

¹ tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:4.

² sn The word of the Lord is a technical expression in OT literature, often referring to a divine prophetic utterance (e.g., Gen 15:1, Isa 1:10, Jonah 1:1). In the NT it occurs 15 times: 3 times as ῥῆμα τοῦ κυρίου (rJhma tou kuriou; Luke 22:61, Acts 11:16, 1 Pet 1:25) and 12 times as λόγος τοῦ κυρίου (logo" tou kuriou; here and in Acts 8:25; 13:44, 48, 49; 15:35, 36; 16:32; 19:10, 20; 1 Thess 1:8; 2 Thess 3:1). As in the OT, this phrase focuses on the prophetic nature and divine origin of what has been said.
