N.T.o. lxx Joe 3:14; Sir. 40:13, of thunder; 3 Macc. 3:2, of a report. It means a loud, unmistakable proclamation.
The word of the Lord (ὁ λόγος τοῦ κυρίου)
The phrase in Paul only in these Epistles. Comp. 2Th 3:1; 1Th 4:15. Comparatively frequent in Acts. Paul has λόγος Θεοῦ or τοῦ Θεοῦ word of God, eight times, and λόγος τοῦ χριστοῦ word of the Christ, once, Col 3:16. The meaning here is the gospel, regarded either as the message proceeding from the Lord, or concerning him. It is the εὐαγγέλιον θεοῦ the gospel of God: see 1Th 2:2, 1Th 2:8, 1Th 2:9; Rom 1:1; Rom 15:16; 2Co 11:7. As Professor Sanday remarks on Rom 1:1, “it is probably a mistake in these cases to restrict the force of the genitive to one particular aspect: all aspects are included in which the gospel is in any way related to God and Christ.”
In every place
A rhetorical exaggeration, signifying the whole known world. It is explained by the extensive commercial relations of Thessalonica. Comp. Rom 1:8; Col 1:6, Col 1:23, 2Co 2:14.
