I. God directed him where to preach this sermon, and when, and to what auditory, v. 2. Let not any censure Jeremiah as indiscreet in the choice of place and time, nor say that he might have delivered his message more privately, in a corner, among his friends that he could confide in, and that he deserved to smart for not acting more cautiously; for God gave him orders to preach in the court of the Lord's house, which was within the peculiar jurisdiction of his sworn enemies the priests, and who would therefore take themselves to be in a particular manner affronted. He must preach this, as it should seem, at the time of one of the most solemn festivals, when persons had come from all the cities of Judah to worship in the Lord's house. These worshippers, we may suppose, had a great veneration for their priests, would credit the character they gave of men, and be exasperated against those whom they defamed, and would, consequently, side with them and strengthen their hands against Jeremiah. But none of these things must move him or daunt him; in the face of all this danger he must preach this sermon, which, if it were not convincing, would be very provoking. And because the prophet might be in some temptation to palliate the matter, and make it better to his hearers than God had made it to him, to exchange an offensive expression for one more plausible, therefore God charges him particularly not to diminish a word, but to speak all the things, nay, all the words, that he had commanded him. Note, God's ambassadors must keep closely to their instructions, and not in the least vary from them, either to please men or to save themselves from harm. They must neither add nor diminish, Deut. iv. 2.
