John Trapp on Jeremiah 49:34

Ver. 34. Againſt Elam] i. e. The Medes, ſay ſome; the Perſians, ſay others; or a people betwixt both: whoſe head-City was that Suſa where Alexander found fifty thouſand talents of gold beſides ſilver. Ariſtagoras alſo thus cheared up his ſouldiers that beſieged it; This City if you can but take, Cum Jove de divitiis licet certetis, you may vie with Jove himſelf for wealth. Theſe Elamites joyned with the Chaldees againſt the Jews, when they firſt waſted Judea, and carried away Jehoiakim: Hence they are here ſo threatned, for their cruelty then.
