I will set wonders in the sky above and signs on the earth below: blood and fire and a haze of smoke.
In context
17‘In the last days, God says, I will pour out my Spirit on all flesh. Your sons and your daughters will prophesy, your young men will see visions, your old men will dream dreams. 18Yes, even on my servants, men and women alike, I will pour out my Spirit in those days, and they will prophesy. 19I will set wonders in the sky above and signs on the earth below: blood and fire and a haze of smoke. 20The sun will turn to darkness and the moon to blood before the day of the Lord comes, that great and shining day. 21And everyone who calls on the name of the Lord will be saved.’
