Acts 2:20 Meaning and Commentary

Acts 2:20

The sun shall be turned into darkness
As at the death of Christ, by a total eclipse of it:

and the moon into blood;
as at the opening of the sixth seal, ( Revelation 6:12 )

before that great and notable day of the Lord come;
when he shall come in power and great glory, as he did in a few years after this, to take vengeance on the Jews, and destroy their nation, city, and temple; in which there was a display of his greatness, and power, and which was awful and "terrible" to them, as in Joel it is called; (See Gill on Matthew 24:29).

Acts 2:20 In-Context

18 In those days I will pour out my Spirit even on my servants—men and women alike— and they will prophesy.

19 And I will cause wonders in the heavens above and signs on the earth below— blood and fire and clouds of smoke.

20 The sun will become dark, and the moon will turn blood red before that great and glorious day of the LORD arrives.

21 But everyone who calls on the name of the LORD will be saved.’

22 “People of Israel, listen! God publicly endorsed Jesus the Nazarene by doing powerful miracles, wonders, and signs through him, as you well know.
