Charles Ellicott Commentary Jeremiah 20:6

"And thou, Pashhur, and all that dwell in thy house shall go into captivity; and thou shalt come to Babylon, and there thou shalt die, and there shalt thou be buried, thou, and all thy friends, to whom thou hast prophesied falsely." — Jeremiah 20:6 (ASV)

Thou shalt come to Babylon ... — The sons of Immer, the section of priests to which Pashur belonged, were found in large numbers at Babylon (Ezra 2:37–38), and it is to be expected that he, as a high official, would be among the captives when Nebuchadnezzar carried into exile all but the poorer sort of the people of the land.

To whom thou hast prophesied lies. — The special predictions in question are not recorded, but we may infer that Pashur was one of those who encouraged the people to fight against the Chaldeans, and to despise Jeremiah’s warnings by holding out the hope that an alliance with Egypt would avert the threatened danger (Jeremiah 14:13; Jeremiah 23:17).
