Just BTW -
Absolutely agree "The Angel of the LORD" = Christ ((as in Judges 13, Exodus 3 etc etc)) but not convinced this is the same person as Michael. To me there are key attributes of all those accounts not present in the brief mentions of Michael in scripture, such as His name being hidden and Him being directly called "God"
I admit that this view makes Hebrews 1 more difficult to navigate, but IMO the way the OT so clearly equates the appearance of this particular 'Messenger' with God, and dileneates Him with the 'Ha' make the difference.
Ok, that is a common ground, or common place, then, to start with. The places that the Son, as you and I believe, is identified as "The Angel of the LORD". (Angel meaning Messenger, not Created, or coming into existence in eternity past, but simply in office/position of messenger for the Father).
Would you agree that this place (Genesis 32:24-30) also refers to the Son?
Gen 32:24 And Jacob was left alone; and there wrestled a man with him until the breaking of the day.
Gen 32:25 And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was out of joint, as he wrestled with him.
Gen 32:26 And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.
Gen 32:27 And he said unto him, What is thy name? And he said, Jacob.
Gen 32:28 And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed.
Gen 32:29 And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there.
Gen 32:30 And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved.
Would you agree that this place (Judges 13:10-22) also refers to the Son (as it seems this is to what you referred to when you said, "as in Judges 13")):
Jdg 13:10 And the woman made haste, and ran, and shewed her husband, and said unto him, Behold, the man hath appeared unto me, that came unto me the other day.
Jdg 13:11 And Manoah arose, and went after his wife, and came to the man, and said unto him, Art thou the man that spakest unto the woman? And he said, I am.
Jdg 13:12 And Manoah said, Now let thy words come to pass. How shall we order the child, and how shall we do unto him?
Jdg 13:13 And the angel of the LORD said unto Manoah, Of all that I said unto the woman let her beware.
Jdg 13:14 She may not eat of any thing that cometh of the vine, neither let her drink wine or strong drink, nor eat any unclean thing: all that I commanded her let her observe.
Jdg 13:15 And Manoah said unto the angel of the LORD, I pray thee, let us detain thee, until we shall have made ready a kid for thee.
Jdg 13:16 And the angel of the LORD said unto Manoah, Though thou detain me, I will not eat of thy bread: and if thou wilt offer a burnt offering, thou must offer it unto the LORD. For Manoah knew not that he was an angel of the LORD.
Jdg 13:17 And Manoah said unto the angel of the LORD, What is thy name, that when thy sayings come to pass we may do thee honour?
Jdg 13:18 And the angel of the LORD said unto him, Why askest thou thus after my name, seeing it is secret?
Jdg 13:19 So Manoah took a kid with a meat offering, and offered it upon a rock unto the LORD: and the angel did wondrously; and Manoah and his wife looked on.
Jdg 13:20 For it came to pass, when the flame went up toward heaven from off the altar, that the angel of the LORD ascended in the flame of the altar. And Manoah and his wife looked on it, and fell on their faces to the ground.
Jdg 13:21 But the angel of the LORD did no more appear to Manoah and to his wife. Then Manoah knew that he was an angel of the LORD.
Jdg 13:22 And Manoah said unto his wife, We shall surely die, because we have seen God.
