Jeremiah 30:5-7

30:5  For thus saith the LORD; We have heard a voice of trembling, of fear, and not of peace.

30:6  Ask ye now, and see whether a man doth travail with child? wherefore do I see every man with his hands on his loins, as a woman in travail, and all faces are turned into paleness?

30:7  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.
