In Previous chapters, the Lord carried out His words of warning. Judah was taken captive to Babylon. Jeremiah writes this letter to them. No doubt they thought very often of their own land of Palestine, and wondered whether they should submit to the rulers of the land where they were held captive. We can see here God’s answer to this question.
V.10 Once more the Lord reminds them that after 70 years He would let them return to their own land. What kindness to tell them the number of years!
V.21 Notice again that the Lord specially names those who refuse to accept His word and who rebelled against Him. He sees and knows the heart of every one and if any refuse His Word, what awful punishment!
V.24-32 Shemaiah pretended to have a message from the Lord, but was really preaching rebellion against the Lord.
