word of the Lord
The general character of the first message from Jehovah to Judah by Jeremiah is threefold:
(1) He reminds Israel of the days of blessing and deliverance, for example (Jeremiah 2:1-7).
(2) He reproaches them with forsaking Him, for example (Jeremiah 2:13).
(3) He accuses them of choosing other, and impotent, gods, for example (Jeremiah 2:10-12); (Jeremiah 2:26-28).
All these messages are to be thought of as inspired sermons, spoken to the people and subsequently written.
Compare (Jeremiah 36:1-32).
