JER 15:8

8 I will cause there to be more widows [in Judah] than [there are grains of] sand on the seashore [HYP]. At noontime, [when people will not be expecting it to happen], I will cause [an enemy army] to attack you, an army that will destroy your young men and cause their mothers to weep. I will cause you to suddenly experience great suffering/pain and become very terrified.
