Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble; but he shall be saved out of it.
That day is great - marked by great calamities (Joel 2:11; Joel 2:31; Amos 5:18; Zephaniah 1:14).
None like it. ... But he shall be saved - (Daniel 12:1). The partial deliverance at Babylon's downfall prefigures
the final complete deliverance of Israel, literal and spiritual, at the downfall of the mystical Babylon (Revelation 18:1-24;
19.)
