Therefore go thou, and read in the roll, which thou hast
written from my mouth
The roll being finished, Baruch is ordered to read it, which was the end of writing it: and since the prophet could not go himself, he sends another in his room, to read the words of the Lord in the ears of the people, in the Lord's house,
upon the fasting day;
the day of atonement; the great fast, which was on the tenth day of the seventh month, in the fourth year of Jehoiakim; and so a different time of reading from that in ( Jeremiah 36:9 ) . This was a very proper time to read it in, when the people were fasting and humbling themselves before the Lord; though some think this was a fast proclaimed by Jehoiakim, to avert the vengeance threatened by the Chaldean army: and also thou shalt read them in the ears of all Judah that come out
of their cities;
to keep the feast of tabernacles; as they did five days after the fast, or day of atonement; and this seems to be the second reading of the roll enjoined.
