Jeremiah 37:4

But Jeremiah tells us that he was then at liberty, coming in and going out among the people It may be that he had been in prison, but that after the rage of the king and of the people had cooled, he might have been set free. It is hence said that he was among the people, that is set at liberty, and at his own disposal, so that he could safely walk through the city; for to come and to go implies that he was free to follow his own business. He is said to come and to go who undertakes this or that concern as he pleases; for men, we know, are not engaged always in the same thing, but do various things as necessity requires. Such, then, was the condition of Jeremiah; he enjoyed common liberty. It is then added, that he was not as yet cast into prison, as it happened soon after. It is further said, that the army of Pharaoh was come out from Egypt to give aid to the Jews, and that thus the siege was raised, for the Chaldeans went forth to meet the Egyptians. At this time, then, Jeremiah received an answer from God. It seems not, therefore, probable that the messengers were sent, when the report spread through the city of the coming of the enemy, but rather when the city was relieved, for the condition of the people was still doubtful, as the liberty of the city and the land depended on the uncertain issue of the war. The Chaldeans had not yet come unto an engagement with the Egyptians. A victory gained by Pharaoh would have given the prospect of peace and safety to Zedekiah and the whole people; but if the Chaldeans gained the day, they saw that the greatest danger was at hand, for they would then be deprived of every assistance.

It was in this state of things that Zedekiah sent messengers to Jeremiah, to solicit his prayers. Thus we see that hypocrites are driven by the fear of God, whom yet they proudly despise, to seek his aid when forced to do so; nor is this done, that they may appear to do so before men, but because God brings them to such straits, that they cannot but feel that they stand in need of his help. They wish, indeed, as I have said, to obliterate every recollection of God, and were they also able to do so, they would rob him of all power and authority; but as they are forced, willing or unwilling, to know that God so reigns in heaven that the whole world is subject to his power, necessity constrains them formally to pray, and, in a manner, to conciliate his favor, or, at least, to try to do so. But as I have already said, they ought to begin with repentance and faith. Hypocrites withdraw themselves as far as they can, both from the promises of God and from the duty of repentance. They so seek God that they at the same time shun him.
