Chapter 9: Sinful people will be punished
Jeremiah says: “Oh that my head were waters, and mine eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people.” (Jeremiah 9:1) The people will be scattered among the heathen, and given wormwood and gall for sustenance. Let not the wise or the mighty glory in their powers. Let he who glories glory in the Lord. The circumcised will be punished alongside the uncircumcised – Israel is uncircumcised in its heart.
The sinful people of Jeremiah’s time and the modern world: “…they bend their tongues like their bow for lies; but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the Lord.” (Jeremiah 9:3)
Chapter 10: Learn not thy heathen!
The house of Israel acts idolatrously, consulting the heavens, worshipping trees, making graven images. False gods have not made the heavens and the earth. The Lord both suffers and is also full of destructive anger.
