What is the timing? It is the same as "the good fig, bad fig vision" (Jeremiah 24:1-10). This was after the early ones were taken away for their good and before the bad ones were destroyed. To put it in terms we can understand, it occurs after the apostasy but before the Tribulation. One can see a parallel between then and now. It is as if Jeremiah is writing this letter to us. We do not have seventy years of exile, God willing, but it still fits because we are in our own exile. Jeremiah advises us what to do.
At first, it seems to run counter to what we should be doing. For instance, the first chapter of Haggai says, "Do not build your house, build My house." But remember we are looking at this from a spiritual standpoint, not physical. So we have to translate Jeremiah's physical advice into spiritual advice. If we study it from that angle, it fits very well.
