I. The orders given to the prophet to preach this sermon; for he had not only a general commission, but particular directions and instructions for every message he delivered. This was a word that came to him from the Lord, v. 1. We are not told when this sermon was to be preached; but are told, 1. Where it must be preached—in the gate of the Lord's house, through which they entered into the outer court, or the court of the people. It would affront the priests, and expose the prophet to their rage, to have such a message as this delivered within their precincts; but the prophet must not fear the face of man, he cannot be faithful to his God if he do. 2. To whom it must be preached—to the men of Judah, that enter in at these gates to worship the Lord; probably it was at one of three feasts, when all the males from all parts of the country were to appear before the Lord in the courts of his house, and not to appear empty: then he had many together to preach to, and that was the most seasonable time to admonish them not to trust to their privileges. Note, (1.) Even those that profess religion have need to be preached to as well as those that are without. (2.) It is desirable to have opportunity of preaching to many together. Wisdom chooses to cry in the chief place of concourse, and, as Jeremiah here, in the opening of the gates, the temple-gates. (3.) When we are going to worship God we have need to be admonished to worship him in the spirit, and to have no confidence in the flesh, Phil. iii. 3.
