John Calvin on Jeremiah 50:30

He confirms the same thing, and shows that the destruction of Babylon would be such, that everything valuable would be destroyed. Fall, he says, shall her strong men in the streets; which is worse than if he had said, “They shall fall in battle.” Babylon was so taken that all her armed men were slain in the middle of the city. Cyrus indeed spared, as it has been already said, the common people; but he slew all the chief men and the armed soldiers. As the Babylonians were taken while keeping a feast, as we read in Daniel, hence Jeremiah mentions the streets. He afterwards adds, —

Jeremiah 50:31

31. Behold, I am against thee, O thou most proud, saith the Lord GOD, of hosts: for thy day is come, the time that I will visit thee.

31. Ecce ego contra to, superbe, dicit Dominus Jehova exercituum quia venit dies tuus, tempus visitationis tuae.
