"Shout out loud! Don't hold back! Raise your voice like a shofar! Proclaim to my people what rebels they are, to the house of Ya`akov (Jacob -emphasis mine) their sins" (Isaiah 58:1 CJB).  "The great day of the LORD is near, it is near, and hasteth greatly, even the voice of the day of the LORD: the mighty man shall cry there bitterly. That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness, A day of the trumpet and alarm against the fenced cities, and against the high towers" (Zeph 1:14-16 KJV).
