Jeremiah 8:14,15 - Joseph Benson’s Commentary on the Old and New Testaments

Let us enter into the defenced cities In these verses the prophet seems to turn to and address his countrymen by way of apostrophe; and, as one of the people that dwelt in the open towns, advises those that were in the like situation to retire with him into some of the fortified cities, and there wait the event with patience; since there was nothing but terror abroad, and the noise of the enemy who had already begun to ravage the country. By this the prophet signifies, that when the Chaldeans should come, there would be no hope of safety left but in fleeing to fortified places, and that none would dare to stay in the open country. He speaks of the thing as already present, because it was soon to happen, and it was represented to him, in his vision, as already present. Let us be silent there, for the Lord hath put us to silence This may mean, that God had suffered the forces of the king of Judah to be so diminished that they were not able to defend the country and open towns, but must of necessity keep themselves cooped up in their fortified cities, and leave the country to be ravaged everywhere by the Chaldeans. And given us water of gall to drink Hath brought us into grievous calamities for the punishment of our sins. We looked for peace We were willing to believe the false prophets, who foretold prosperous times. For a time of health Or, for a time in which we should be cured; that is, for a time of peace, in which we might recover our strength.
