Joel 2:10-12 The earth quakes before them; the heavens tremble. The sun and the moon are darkened and the stars withdraw their shining. 11 And the Lord utters His voice before His army, for His host is very great, and [they are] strong and powerful who execute [God’s] word. For the day of the Lord is great and very terrible, and who can endure it? 12 Therefore also now, says the Lord, turn and keep on coming to Me with all your heart,with fasting, with weeping, and with mourning.
