Jeremiah is to take his stand in the court of the Lord's house; i.e. the outer court, where the people assembled (comp. Jeremiah 19:14), and preach unto all the cities of Judah; i.e. to the pilgrims who had come from the provincial towns (comp.
Jeremiah 11:12). His discourse is not to be an eloquent appeal to the feelings, but a strict and peremptory announcement; he is to diminish (or, subtract) not a word (comp. Deuteronomy 4:2; Deuteronomy 12:32; Revelation 22:19).
