A remnant goes to Egypt, including the king’s two daughters. Even though scripture says that the words of Jeremiah end with Jer. 51:64 there are other writings that tell of Jeremiah and Baruch leaving Egypt with the king’s daughters. The significance of this will be discussed later.

Jeremiah 14 records men who came to offer grain offerings and burn incense in the house of the Lord.  This must have been the equivalent of the synagogue.  They weren't offering burnt offerings in the way of animal sacrifices because they had no temple and no priests.  Remember, they were no longer able to celebrate and rejoice during the feast days.  

Jeremiah warns the Hebrews living in Egypt that God will bring disaster on them if they continue in their evil ways. The response of the people goes far beyond impudent! They were mocking God. They suffered the consequences.

Gal 6:7
Do not be deceived: God cannot be mocked. A man reaps what he sows.
Reaping can also have many positive aspects. Especially if we sow in righteousness. (Hos 10:12) Sow to yourselves in righteousness, reap according to kindness; break up your fallow ground; for it is time to seek Jehovah, till he come and rain righteousness upon you.
