The Day of the Lord#a. [3:1] Is 44:3; Ez 39:28–29; Acts 2:17–21.
1#In many places in the Old Testament, Hebrew ruah is God’s power, or spirit, bestowed on chosen individuals. The word can also mean “breath” or “wind.” In this summary introduction to his second speech, Joel anticipates that the Lord will someday renew faithful Judahites with the divine spirit. In Acts 2:17–21 the author has Peter cite Joel’s words to suggest that the newly constituted Christian community, filled with divine life and power, inaugurates the Lord’s Day, understood as salvation for all who believe that Jesus of Nazareth is the Christ. It shall come to pass
I will pour out my spirit upon all flesh.
Your sons and daughters will prophesy,
your old men will dream dreams,
your young men will see visions.
2Even upon your male and female servants,
in those days, I will pour out my spirit.
3I will set signs in the heavens and on the earth,
blood, fire, and columns of smoke;
4The sun will darken,
the moon turn blood-red,
Before the day of the Lord arrives,
that great and terrible day.#b. [3:4] Jl 2:10; Mal 3:23.
5Then everyone who calls upon the name of the Lord
will escape harm.
For on Mount Zion there will be a remnant,
as the Lord has said,
And in Jerusalem survivors
whom the Lord will summon.#c. [3:5] Ob 17–18; Rom 10:13.
