Keeping the temple gate.
It was probably not the outer gate, but one of the gates which led from the outer to the inner or upper court (cf. Jeremiah 19:14; Jeremiah 26:10; Jeremiah 36:10). "From this point the prophet could view the whole assembly of the people in the outer court, as well as the gates leading from without into it' (Lange). Christ seems to have stood thus at times.
I. THE PREACHER OF TRUTH DOES WELL TO CHOOSE THE MOST IMPRESSIVE POSITIONS, OCCASIONS, AND CIRCUMSTANCES FOR THE DELIVERY OF HIS MESSAGE. The great aim of the preacher is to get a hearing for what he has to say. Tact (to a certain degree), artistic juxtaposition and arrangement, sympathy with the spirit of the times, etc; are indispensable qualities to him who would give the Word of God bold and effective expression. Public occasions may, therefore, frequently be utilized for special services, etc. Passing movement and contemporary events may give fresh interest to permanent truth. A curious ingenuity is sometimes exhibited in making the preacher inconspicuous and reducing his office to a matter of routine. He ought always to feel that his message is an extraordinary one, requiring all the earnestness and effort of which he is capable to convey it with due effect. And even then it must have suffered at his hands, and in much he will be an unprofitable servant.
II. RELIGIOUS OBSERVANCE MAY BE VERY FASHIONABLE, AND ALL BUT UNIVERSAL, WHERE THERE IS LITTLE REAL RELIGION. One has to distinguish between the outward and the inward, the religion of rite and ceremony and that of the heart. Here apparently the representatives of "all Judah" were assembled, and yet it was no sign of national piety, but rather the contrary. Instead of the carnal nature Being checked and corrected, it was directly fostered by such worship. Public worship is a phrase which often includes elements that have nothing to do with the worship of God. That the services of God's house should be chaste and attractive will be generally admitted. But architectural adornments, musical accessories of an ornate or merely artistic nature, displays of rhetoric, and similar additions to the essential character of the worship, may prove popular and entertaining, and yet be spiritually pernicious. In the case of Judah the whole worship was on a low intellectual and spiritual key. The gods of heathenism and Jehovah were worshipped alike, and the licentious rites of idolatry mingled with the sacrifices of the Law. This had resulted in the temple being polluted and becoming a "den of thieves." Our aims in worship, the purity and concentration of our hearts, the moral relation between our every-day life and our temple service, have all very intimately to do with the question of the value of public religious observances.
III. RIGHTEOUSNESS OUGHT TO BE PRELIMINARY TO WORSHIP. "Amend your ways and your doings" is the demand the prophet makes in proof of the genuineness of their worship. Religion is a matter of life, and not of showy observances and empty protestations. The best proof that we intend serving God is that we have already begun to do so in business and morals. This duty, although difficult, is the best preparation for exalted spiritual experiences and sincere adoration. Men are not fit to appear before God when their misdeeds are still being repeated and their moral habits are not under the influence of his Spirit.
IV. UNREAL WORSHIP OF GOD IS CERTAIN TO BE DETECTED AND EXPOSED. We can imagine the shame of the nobility and people whom the prophet from his unlooked-for vantage-point so sharply rebuked.—M.
