Charles Spurgeon Commentary Jeremiah 30:6-7

"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? 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." — Jeremiah 30:6-7 (ASV)

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? 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.

This passage evidently alludes to a time of very great distress, when men's hearts were swollen within them as if they would burst from sheer grief. Not simply one here or there, but the great mass of the people seemed to be in severe trouble; even the stout-hearted ones began to feel inward pangs of affliction; yet it was then that the Lord said, It is even the time of Jacob's trouble; but he shall be saved out of it.
