“And afterward,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your old men will dream dreams,
your young men will see visions.
Even on my servants, both men and women,
I will pour out my Spirit in those days.
I will show wonders in the heavens
and on the earth,
blood and fire and billows of smoke.
The sun will be turned to darkness
and the moon to blood
before the coming of the great and dreadful day of the Lord.”
~ Joel 2:28-31
The 4th blood moon date of this tetrad is September 28
Israeli Jews will be celebrating the end of Shemiteh at the Western Wall on that date, so I have read
Also in Acts 2:14-41 New International Version (NIV)
Peter Addresses the Crowd
14 Then Peter stood up with the Eleven, raised his voice and addressed the crowd: “Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. 15 These people are not drunk, as you suppose. It’s only nine in the morning! 16 No, this is what was spoken by the prophet Joel:
17 “‘In the last days, God says,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your young men will see visions,
your old men will dream dreams.
18 Even on my servants, both men and women,
I will pour out my Spirit in those days,
and they will prophesy.
19 I will show wonders in the heavens above
and signs on the earth below,
blood and fire and billows of smoke.
20 The sun will be turned to darkness
and the moon to blood
before the coming of the great and glorious day of the Lord.
21 And everyone who calls
on the name of the Lord will be saved.
