Charles Ellicott Commentary Jeremiah 27:8

"And it shall come to pass, that the nation and the kingdom which will not serve the same Nebuchadnezzar king of Babylon, and that will not put their neck under the yoke of the king of Babylon, that nation will I punish, saith Jehovah, with the sword, and with the famine, and with the pestilence, until I have consumed them by his hand." — Jeremiah 27:8 (ASV)

That nation will I punish. — Better translation: I will visit. The three forms of punishment go naturally together. In Ezekiel 14:21, they appear, with the addition of the "noisome beast," as the four sore judgments of God.
