Genesis 16:7-13 - the AOTL appears separately from the LORD and speaks about something the LORD said.
Revelation 19:9-10, Revelation 22:9 - the AOTL refused to be worshipped as God.
Judges 6:11-32 - the AOTL is a messenger of God, the angel leaves and God stays
Exodus 3:2 - the AOTL is a messenger of God
Judges 2:1 - the AOTL exercised delegated authority from God
Zechariah 1:13,14 - The angel of the LORD and the LORD speak to one another.
Matthew 1:24 - The angel of the Lord is present after Jesus was already a baby
Matthew 28:1-5 - The angel of the Lord is present after Jesus was resurrected.
The Angel of the Lord in the OT was the pre incarnate Son which is why He is identified as YHWH and worshiped as God unlike the created angels who are not worshiped.
Gen 22:11-14
But the angel of the Lord called out to him from heaven, "Abraham! Abraham!"
"Here I am," he replied.
12 "Do not lay a hand on the boy," he said. "Do not do anything to him. Now I know that you fear God, because you have not withheld from me your son, your only son."
13 Abraham looked up and there in a thicket he saw a ram caught by its horns. He went over and took the ram and sacrificed it as a burnt offering instead of his son.
14 So Abraham called that place The Lord Will Provide. And to this day it is said, "On the mountain of the Lord it will be provided."
Exodus 3:2, 5
And the angel of the LORD appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed…And he said, Draw not nigh thither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground.”
Judg 6:11-28
The angel of the Lord came and sat down under the oak in Ophrah that belonged to Joash the Abiezrite, where his son Gideon was threshing wheat in a winepress to keep it from the Midianites.
12 When the angel of the Lord appeared to Gideon, he said, "The Lord is with you, mighty warrior."
13 "But sir," Gideon replied, "if the Lord is with us, why has all this happened to us? Where are all his wonders that our fathers told us about when they said, 'Did not the Lord bring us up out of Egypt? But now the Lord has abandoned us and put us into the hand of Midian."
14 The Lord turned to him and said, "Go in the strength you have and save Israel out of Midian's hand. Am I not sending you?"
15 "But Lord,” Gideon asked, "how can I save Israel? My clan is the weakest in Manasseh, and I am the least in my family."
16 The Lord answered, "I will be with you, and you will strike down all the Midianites together."
17 Gideon replied, "If now I have found favor in your eyes, give me a sign that it is really you talking to me.
18 Please do not go away until I come back and bring my offering and set it before you."
And the Lord said, "I will wait until you return."
19 Gideon went in, prepared a young goat, and from an ephah of flour he made bread without yeast. Putting the meat in a basket and its broth in a pot, he brought them out and offered them to him under the oak.
20 The angel of God said to him, "Take the meat and the unleavened bread, place them on this rock, and pour out the broth." And Gideon did so.
21 With the tip of the staff that was in his hand, the angel of the Lord touched the meat and the unleavened bread. Fire flared from the rock, consuming the meat and the bread. And the angel of the Lord disappeared.
22 When Gideon realized that it was the angel of the Lord, he exclaimed, "Ah, Sovereign Lord! I have seen the angel of the Lord face to face!"
23 But the Lord said to him, "Peace! Do not be afraid. You are not going to die."
24 So Gideon built an altar to the Lord there and called it The Lord is Peace. To this day it stands in Ophrah of the Abiezrites.
25 That same night the Lord said to him, "Take the second bull from your father's herd, the one seven years old.Tear down your father's altar to Baal and cut down the Asherah pole beside it.
26 Then build a proper kind of altar to the Lord your God on the top of this height. Using the wood of the Asherah pole that you cut down, offer the second bull as a burnt offering."
27 So Gideon took ten of his servants and did as the Lord told him. But because he was afraid of his family and the men of the town, he did it at night rather than in the daytime.
28 In the morning when the men of the town got up, there was Baal's altar, demolished, with the Asherah pole beside it cut down and the second bull sacrificed on the newly built altar!
Well the main function or a general definition of a "shaliach" is as follows:
A shaliaḥ (שָלִיחַ; pl. שְלִיחִים, sheliḥim) in Halakha is a Jewish legal or agent. Accordingly, a shaliaḥ performs an act of legal significance for the benefit of the sender, as opposed to him or herself.
en.wikipedia.org/wiki/Shaliach
A Chabad shliach (שליח, pl. שליחים/שלוחים, shlichim/shluchim) is a Chabad member sent out to promulgate Judaism and Chasidut around the world. Chabad shluchim today number about 4,000 worldwide, and can be found in many of even the most remote worldly locales.

Now, I am bringing this up for a very good reason and I want to cut to the chase of my point in this little exercise. The basic job of a "shaliach or the definition is an agent sent on a specfic mission to represent the interst of someon else. In short there are restrictions to the function of a shaliach and I will give you the best example.
Now, you have at Genesis 16:7 the very first appearance of the angel of the Lord. If you read the context from verse 7 to Genesis 17:1-2 you will discover that the Lord God Almighty is the speaker even though the the angel of the Lord is actually speaking. At verse 10 the angel of the Lord says that He will greatly multiply the descendents of Hagar. Then at Genesis 17:1 and 2 it's the Lord God Almighty who will multiply his descendents. You cannot get away from the fact that the same being is taking in the passages. Even at Genesis 16:13 Hagar says I have see the Lord God and am still alive.
Now, lets jump to Genesis 22 where God is going to test Abraham. You have the Lord God Almighty speaking from Genesis 22:1-10. There is no question about this fact. At verse 11 it states, "But the angel of the Lord called to him (Abraham) from heaven and said, "Abraham, Abraham!" And he said, "Here I am." Then at verse 15 the angel of the Lord called to Abraham from heaven a second time." (Note: why does the angel of the Lord have to call out for God Himself a second time from heaven?) Is not the Lord God Himself capable of calling out from heaven Himself. I mean He did call out from heaven at Mark 1:11. He did not need the so-called shaliah then.
After the angel of the Lord calls out from heaven the second time which is Genesis 22:15 here is what this so-called shaliach/emissary says, "By Myself I have sworn, declares the Lord, because you have done this thing, and have not withheld you son, you only son. Indeed, I will greatly multiply your seed as the stars of the heavens, and as the sand which is on the seashore etc."
So you see from following the sequence of events a shaliach is limited or he can only do so much on behalf of the sender. He cannot swear an oath for the sender as you see the scriptures say. He cannot multiply the seed of anyone as you see the scriptures say.
Not only that but the real kicker of all of this is found in the NT at Hebrews 6:13. The writer of the Hebrews states, "For when God made the promise to Abraham, SINCE HE COULD SWEAR BY NO ONE GREATER, HE SWORE BY HIMSELF, VS14, SAYING, "I WILL SURELY BLESS YOU , AND I WILL MULTIPLY YOU." This text is referring back to Genesis 22 and Abraham. A shaliach cannot swear an oath on behalf of the sender and it even says God swore by Himself. In short, the shaliach argument will not work and I maintain that the messenger of the Lord is the pre-incarnate Jesus Christ
hope this helps !!!
