New American Standard Bible
17 ‘(A)And it shall be in the last days,’ God says,
‘That I will pour out My Spirit on all [a]mankind;
And your sons and your daughters will prophesy,
And your young men will see visions,
And your old men will [b]have dreams;
18 And even on My male and female [c]servants
I will pour out My Spirit in those days,
And they will prophesy.
19 And I will [d]display wonders in the sky above
And signs on the earth below,
Blood, fire, and [e]vapor of smoke.
20 The sun will be turned into darkness
And the moon into blood,
Before the great and glorious day of the Lord comes.
21 And it shall be that (B)everyone who calls on the name of the Lord will be saved.’
