18. And even on my male slaves and on my female slaves I will pour out my Spirit in those days, and they will prophesy.
19. And I will cause wonders in the heaven above and signs on the earth below, blood and fire and vapor of smoke.
20. The sun will be changed to darkness and the moon to blood, before the great and glorious day of the Lord comes.
21. And it will be that everyone who calls upon the name of the Lord will be saved.’
