A day is SET
A time of salvation and deliverance for the righteous, the day in which Jehovah himself is highly exalted as the Supreme One. Thus, in a double way it is uniquely and exclusively Jehovah’s great day.
This day is detailed in the Scriptures as a time of battle, a great and fear-inspiring day of darkness and burning anger, a day of fury, distress, anguish, desolation, and alarm. “What, then, will the day of Jehovah mean to you people?” God asked wayward Israel by the mouth of his prophet Amos. This: “It will be darkness, and no light, just as when a man flees because of the lion, and the bear actually meets him; and as when he went into the house and supported his hand against the wall, and the serpent bit him.” (Am 5:18-20).
Isaiah was told: “Look! The day of Jehovah itself is coming, cruel both with fury and with burning anger.” (Isa 13:9) “That day is a day of fury, a day of distress and of anguish, a day of storm and of desolation, a day of darkness and of gloominess, a day of clouds and of thick gloom.” (Zep 1:15) During such a time of trouble, one’s money is absolutely worthless. “Into the streets they will throw their very silver . . . Neither their silver nor their gold will be able to deliver them in the day of Jehovah’s fury.”—Eze 7:19; Zep 1:18.
Zephaniah’s counsel: “Before the statute gives birth to anything, before the day has passed by just like chaff, before there comes upon you people the burning anger of Jehovah, before there comes upon you the day of Jehovah’s anger, seek Jehovah, all you meek ones of the earth, who have practiced His own judicial decision. Seek righteousness, seek meekness. Probably you may be concealed in the day of Jehovah’s anger.”—Zep 2:2, 3.
