Jeremiah 33:14
Behold, the days come, saith the LORD, that I will perform that good thing which I have promised unto the house of Israel and to the house of Judah. Behold, the days come, saith the LORD, that I will perform that good thing which I have promised unto the house of Israel and to the house of Judah.
The promise came during Jerusalem's final siege, when hope had fled and Jeremiah was imprisoned for urging surrender. It was given to the house of Israel and to the house of Judah, especially to the faithful remnant, as assurance that the Lord would fulfill the good He had promised them. Though Jerusalem faced destruction and its people would go into captivity, the promised good meant return and restoration.
The land would again be inhabited, and the people would worship and rejoice, and this restoration was certain despite present desolation. The revelation brought comfort by showing God's willingness to forgive and save. The passage calls for trust in the promised good, to be claimed by living faith so that blessing and light may be received.
