Commentaries:
Jeremiah wrote this over 400 years after Israel's rejection of God as King and about 840 years after making the covenant at Mount Sinai. Even though by the time of this writing God had divorced the Great Harlot Israel, He still continued to have a fractious relationship with her in order to continue the outworking of His purpose and to fulfill His promises to Abraham, including all the end-time prophecies. In other words, He was not yet finished with Israel.
