Then the LORD said unto me, Proclaim all these words in the cities of Judah, and in the streets of Jerusalem, saying, Hear ye the words of this covenant, and do them.
Proclaim all these words in the cities of Judah. Jeremiah was to take a prophetic tour throughout Judah, to proclaim everywhere the denunciations in the book of the law found in the temple.
Hear ye the words of this covenant, and do them - (Romans 2:13; James 1:22, "Be ye doers of the word, and not bearers only").
