Midrasz do Jeremiasza 31:38

VII) Behold days are [coming], declares the LORD (Jeremiah 31:38) It is written lacking: For behold days are, declares the LORD. This is an obscure matter, and we could say that this is tidings for far-off times and many days, just as we read coming from the margin, bringing near the end-times and bringing near the tidings of reading coming in the commandments of the prophet. May the Merciful One accelerate the end-times.
