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).

19 I will show miracles in the sky and on the earth: blood, fire, and thick smoke.

20 The sun will become dark, the moon red as blood, before the overwhelming and glorious day of the Lord will come.

21 Then anyone who calls on the Lord will be saved.'

22 "People of Israel, listen to these words: Jesus from Nazareth was a very special man. God clearly showed this to you by the miracles, wonders, and signs he did through Jesus. You all know this, because it happened right here among you.
