Jeremiah 50:1

The word that the Lord spake against Babylon and against the land of the Chaldeans by Jeremiah, the prophet, when Seraiah, to whom it was committed, was sent to Babylon, 51:59-60. It seems that the various prophecies against Babylon were collected at this time, to be sent as one message, partly to pronounce the doom of the oppressor, 25:12, partly to console the captive Jews and to remind them of the eventual end of their captivity.
