Charles Ellicott Commentary Jeremiah 9:6

"Thy habitation is in the midst of deceit; through deceit they refuse to know me, saith Jehovah." — Jeremiah 9:6 (ASV)

Your habitation ... —The words may be an individualized, and therefore more emphatic, reproduction of the general warning of Jeremiah 9:4. It is, however, better to take them as spoken by Jehovah to the prophet individually. The Septuagint, following a different reading and punctuation, translates “usury upon usury, deceit upon deceit; they refuse to know Me, saith the Lord.” And this has been adopted by Ewald, among recent commentators.
