Albert Barnes Commentary Jeremiah 3:17

"At that time they shall call Jerusalem the throne of Jehovah; and all the nations shall be gathered unto it, to the name of Jehovah, to Jerusalem: neither shall they walk any more after the stubbornness of their evil heart." — Jeremiah 3:17 (ASV)

The throne of the Lord - Yahweh’s throne shall not be the ark, but Jerusalem, that is, the Christian Church (Revelation 21:2; Galatians 4:26).

To Jerusalem - The Septuagint and Syriac are probably right in omitting this word.

Imagination ... - Stubbornness (margin). A word always used in a bad sense, for “obstinacy.”
