Jamieson, Fausset & Brown, on Jer 8:19

“Behold the voice of the daughter my people from a far country: Is not the Lord in Sion, or is not her king in her? why then have they provoked me to wrath with their idols, and strange vanities?”

“The prophet in vision hears the cry of the exiled Jews, wondering that God should have delivered them up to the enemy, seeing that He is Zion's king, dwelling in her (Mic 3:11). In the latter half of the verse God replies that their own idolatry, not want of faithfulness on His part, is the cause. because of them that dwell in a far country--rather, "from a land of distances," that is, a distant land (Isa 39:3). English Version understands the cry to be of the Jews in their own land, because of the enemy coming from their far-off country. strange vanities--foreign gods.”
