Judges 13:17-23

[17]Then Manoah said to the Angel of the Lord, “What is Your name, that when Your words come to pass we may honor You?”

[18]And the Angel of the Lord said to him, “Why do you ask My name, seeing it is wonderful?”
[19]So Manoah took the young goat with the grain offering, and offered it upon the rock to the Lord. And He did a wondrous thing while Manoah and his wife looked on—
[20]it happened as the flame went up toward heaven from the altar—the Angel of the Lord ascended in the flame of the altar! When Manoah and his wife saw this, they fell on their faces to the ground.
[21]When the Angel of the Lord appeared no more to Manoah and his wife, then Manoah knew that He was the Angel of the Lord.
[22]And Manoah said to his wife, “We shall surely die, because we have seen God!”
[23]But his wife said to him, “If the Lord had desired to kill us, He would not have accepted a burnt offering and a grain offering from our hands, nor would He have shown us all these things, nor would He have told us such things as these at this time.”

Was this Angel of God , God Himself?

EFULEFU1:

Was this Angel of God , God Himself?

Angel of God, just as the story says.

Short answer is NO!

Jehovah God has always been using his Angel/messenger to transmit his messages.
They're God's Spokesman.
So, When Manoah and his wife addressed Materialized God's Angelic Spokesman, it was as if they were talking to God himself.
This angel spoke precisely what God wanted to have said to them and they're acting like mouthpiece.

So, They were able to see the angel and the glory of Jehovah reflected by him, but they were not able to see God.
This agree with apostle John’s statement: “No man has seen God at any time." (John 1:18)
