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.
Jeremiah 33:12 Thus saith the LORD of hosts; Again in this place, which is desolate without man and without beast, and in all the cities thereof, shall be an habitation of shepherds causing their flocks to lie down.
Jeremiah 33:13 In the cities of the mountains, in the cities of the vale, and in the cities of the south, and in the land of Benjamin, and in the places about Jerusalem, and in the cities of Judah, shall the flocks pass again under the hands of him that telleth them, saith the LORD.
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.
Jeremiah 33:15 In those days, and at that time, will I cause the Branch of righteousness to grow up unto David; and he shall execute judgment and righteousness in the land.
Jeremiah 33:16 In those days shall Judah be saved, and Jerusalem shall dwell safely: and this is the name wherewith she shall be called, The LORD our righteousness.
The verse centers on "behold", "days", "come", "saith", "lord", "perform", "good", and "promised". It is saying that the verse draws attention to "behold" and "days", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "In the cities of the mountains in..." into verse 15's "In those days and at that time...", so "behold" and "days" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "behold" and "days" with trust shaped by these words, not by a vague optimism outside the passage.
