¹ 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; here and in Luke 22:61, Acts 11:16) and 12 times as λόγος τοῦ κυρίου (logo" tou kuriou; Acts 8:25; 13:44, 48, 49; 15:35, 36; 16:32; 19:10, 20; 1 Thess 1:8, 4:15; 2 Thess 3:1). As in the OT, this phrase focuses on the prophetic nature and divine origin of what has been said.
