For a voice declareth from Dan - Dan was a city in the tribe of Dan, north of Jerusalem; the first city in Palestine, which occurs in the way from Babylon to Jerusalem.
Affliction from Mount Ephraim - Between Dan and Jerusalem are the mountains of Ephraim. These would be the first places attacked by the Chaldeans; and the rumor from thence would show that the land was invaded.
Dan - The border-town of Palestine on the north Deuteronomy 34:1.
Mount Ephraim - The northern boundary of Judaea itself. The invading army presses on so rapidly, that scarcely have the news arrived of its appearance at Dan, before fresh messengers announce that it has traversed the whole length of Galilee, and is now defiling through the mountains of Samaria.
Affliction - The same word, aven, occurs in Jeremiah 4:14, and apparently there is a play upon its double meaning: for from a root signifying worthlessness, it is used both for wickedness and for misery. Thus, the “iniquity” of Judah proves also, to be her “affliction,” as being the cause of the ruin inflicted by the enemy.
