No. There is nothing in the bible to suggest it. Angels in the capacity of agents of YHWH spoke YHWH's own words. They referred to themselves as YHWH because they communicated his words and acted with his power. Just because they were messengers didn't mean that they were more than angels.
The answer I'm about to give is not only for you cjab, it's for 101G as well. The Hebrew word for "angel" is "malak." This word simply means "messenger." And yes, it can mean an actual angel but it is the context that determines the meaning. For instance at Malachi 3:1, "Behold, I am going to send my "malak/angel/messenger," and he will clear the way before Me. And the Lord, whom you seek, will suddenly come to His temple; (who do you think that is?) and the "malak/angel/messenger" of the covenant, in whom you delight, behold, He is coming, says the Lord of hosts." (Who do you think the messenger of the covenant is?)
The angel/messenger who will clear the way of the Lord is none other than John the Baptist. He's a human "messenger" Just read Mark 1:1-4. And btw, the prophet "Malachi" who is human, well his name is from the Hebrew word "malak" and of course he's a human being and not an angel.
Now, lets look at Genesis 16, starting at vs7, This is the first reference of the angel of the Lord as the angel of the Lord. "Now the angel of the Lord found her by a spring of water in the wilderness, by the spring on the way to Shur. Paraphrasing, Vs8, "Hagar is fleeing her mistress Sarai. Vs9, Then the angel of the Lord said to return to her mistress." Vs10, "Moreover, the angel of the Lord said to her, "I will greatly multiply your descendants so that they shall be too many to count."
Vs11, "The angel of the Lord said she is with child, a son. Vs12, "He will be a wild donkey of a man etc. The Arabs today are his descendants. Vs13, The she called the name of the Lord who spoke to her, Thou art a God who sees;" for she said, Have I even remained alive here after seeing Him?" (And as a side note Ishmael is where the Arabs came from).
At Genesis 17:1-2, "Now when Abram was ninety-nine years old the LORD appeared to Abram and said to him, "I am God Almighty; Walk before, and be blameless, vs2, And I will establish My covenant between Me and you, And I will multiply you exceedingly."
Here's a question? Is the being, the angel of the Lord that multiplied Hagar's descendants the same being who was identified as God Almighty who multiplied Abraham's descendant at Genesis 17:1-2? Think about it?
Moving on to Genesis 18, it says at vs1, "Now the Lord appeared to him/Abraham by the oaks of Mamre while he was sitting at the tent door in the heat of the day." Paraphrasing again. "Vs2, Abraham sees three men. Vs3-6, Abraham offers water to wash their feet and food to eat. Vs9, Abraham was asked where his wife was? Vs10, And HE SAID, "I will surely return to you at this time next year, and behold, your wife Sarah shall have a son."
Vs13, "And the Lord said to Abraham, why did Sarah laugh etc.? Vs14, "Is anything too difficult for the Lord? One of the men was the angel of the Lord and the other two men were actual angles. Look at Genesis 18:33, "And as soon as He had finished speaking to Abraham, the LORD departed; and Abraham returned to his place." Genesis 19:1, "Now the TWO ANGELS came to Sodom in the evening as Lot was sitting in gate of Sodom, etc.
Moving on to Genesis 22. Vs1, God tested Abraham. Vs9, "Then they came to the place of which GOD had told him; and Abraham built the altar there etc. Vs10, "And Abraham stretched out his hand and took the knife to slay his son."
Vs11, "But the angel of the Lord called to him from heaven, and said, "Abraham, Abraham!" And he said, "Here I am." Vs12, "And he said, "Do not stretch out your hand against the lad, and do nothing to him, for now I know that you fear God, since you have not withheld you son, your only son from Me." Vs13-14, God supplies Abraham with a sacrifice.
Vs15, "Then the angel of the Lord called to Abraham a second time from heaven, vs16, "and said, By Myself I have sworn, declares the Lord, because you have done this thing, and have not withheld your son, your only son, (side note, Abraham had an older son named Ishmael by Hagar who was older than Isaac).
Vs17, "indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens, and as the sand which is on the seashore; and your seed shall possess the gate of their enemies."
Some make the claim that the angel of the Lord is speaking on God's behalf. (Like you cjab). He's the agent or in Hebrew a "shaliach." This is known at the "Jewish Law of Agency." The Law of Agency deals with the status of a person (known as the agent) acting by direction of another, (the principal.) In this case your "positing" that the angel of the Lord, the agent is acting for the principal who is God. There is one BIG problem why in this case the law of agency does not apply.
Look at whatHebrews 6:13-14 has to say. "For when God made the promise to Abraham, SINCE He could not swear BY NO OTHER, HE SWORE BY HIMSELF, Vs14, saying, I will surely bless you, and I will surely multiply you." Notice vs16, "For men swear by one greater than themselves, and with them an oath given as confirmation is an end of every dispute."
In other words, in taking oaths, men swear by God who is greater than they are. They do so in order to convince other men that they are truthful and intend to abide by their promises. Also, angels cannot swear oaths on behalf of God Himself. Swearing an oath is a matter of one's conscience. If you saw a crime and were ask to testify what you saw, you can't send your Uncle Harry to wear that he saw it. In fact, even you could not appear in a court for some reason, i.e injured or hospitalized the court would send someone to "depose" you by sworn affidavit.
The bottom line, the angel of the Lord is not an actual angel but the pre-incarnate Jesus Christ serving as a messenger of God and as an intermediary on behalf of the nation of Israel. A real good example is at Judges 2:1, "Now the angel of the Lord came up from Gilgad to Bochim. And he said, "I brought you up out of the Egypt and led you into the land which I HAVE SWORN TO YOUR FATHERS; and I said, "I will never break My covenant with you." I'll be happy to answer any and all questions? (Some of the legal aspects of this was taken from the Jewish Virtual Library). PS: I just remembered that an angel can swear an oath on behalf of himself. Revelation 10:5-6.
IN THE ANGEL OF THE LORD,
