John Trapp on Jeremiah 4:15

Ver. 15. For a voice declareth from Dan] which was firſt called Laiſh, then Dan, and after that (in honour of Tiberius Caeſar) Caeſarea Philippi. It was the utmoſt bound of Iſrael Northward:Joſeph. Antiq. lib. 18. and therehence came a rumour of the enemy entering, and making his firſt impreſſion into the Land; and ſo, by Mount Ephraim, to the Jews of Jeruſalem. This, Jeremy by a ſpirit of Prophecy foretelleth long before, againſt their vain confidence of better.

And publiſheth affliction] The ſame Hebrew word ſignifieth vanity or iniquity in the verſe afore-going. Sin is the mother of miſery and moleſtation.
