Joel 2:2-13

A day of darkness and gloom, A day of clouds and of thick [dark] mist, Like the dawn spread over the mountains; There is a [pagan, hostile] people numerous and mighty, The like of which has never been before Nor will be again afterward Even for years of many generations. Before them a fire devours, And behind them a flame burns; Before them the land is like the Garden of Eden, But behind them a desolate wilderness; And nothing at all escapes them. Their appearance is like the appearance of horses, And they run like war horses. Like the noise of chariots They leap on the tops of the mountains, Like the crackling of a flame of fire devouring the stubble, Like a mighty people set in battle formation. [Rev 9:7, 9] Before them the people are in anguish; All faces become pale [with terror]. They run like warriors; They climb the wall like soldiers. They each march [straight ahead] in line, And they do not deviate from their paths. They do not crowd each other; Each one marches in his path. When they burst through the defenses (weapons), They do not break ranks. They rush over the city, They run on the wall; They climb up into the houses, They enter at the windows like a thief. The earth quakes before them, The heavens tremble, The sun and the moon grow dark And the stars lose their brightness. [Rev 9:2-4; 16:14] The LORD utters His voice before His army, For His camp is very great, Because strong and powerful is he who [obediently] carries out His word. For the day of the LORD is indeed great and very terrible [causing dread]; Who can endure it? [Is 26:20, 21; 34:1-4, 8; Rev 6:16, 17] “Even now,” says the LORD, “Turn and come to Me with all your heart [in genuine repentance], With fasting and weeping and mourning [until every barrier is removed and the broken fellowship is restored]; Rip your heart to pieces [in sorrow and contrition] and not your garments.” Now return [in repentance] to the LORD your God, For He is gracious and compassionate, Slow to anger, abounding in lovingkindness [faithful to His covenant with His people]; And He relents [His sentence of] evil [when His people genuinely repent].
