Amos 3:6

Is a horn (Amos 2:2) blown in a city, and are the people not in alarm?] Of course they are: for they know it to be the signal of approaching danger. The horn was blown as a summons to repel an invader, &c. (Hosea 5:8; Jeremiah 6:1; Ezekiel 33:3 f.; 1 Corinthians 14:8).

will evil happen in(R.V. befall) a city, and Jehovah hath not doneit?] Will evil i.e. calamity, misfortune, as 1 Samuel 6:9 happen in a city without having its sufficient cause in Jehovah's purpose? The Hebrews often took no account of what we term -secondary causes"; and a calamity, such as famine or pestilence, which might be the natural consequence of some physical antecedent, is thus referred here directly to Jehovah's operation.
