Shalom, Mishpachah.

Okay, as one might be able to tell from the verses cited so far, I consider the fulfillment of Dani'el 9:27 in part to be the Davidic Covenant given to David and his descendants, including the "Son of David," the Messiah Himself, Yeshua`.

Now, the obvious question would be: WHEN was the Davidic Covenant "confirmed" by Yeshua` when Gavri'el said, "he shall confirm the covenant with many for one week?"

Consider the logic of the following:

1 Chron. 22:7-12
7 And David said to Solomon, My son, as for me, it was in my mind to build an house unto the name of the Lord my God:
8 But the word of the Lord came to me, saying, Thou hast shed blood abundantly, and hast made great wars: thou shalt not build an house unto my name, because thou hast shed much blood upon the earth in my sight.
9 Behold, a son shall be born to thee, who shall be a man of rest; and I will give him rest from all his enemies round about: for his name shall be Solomon, and I will give peace and quietness unto Israel in his days.
10 He shall build an house for my name; and he shall be my son, and I will be his father; and I will establish the throne of his kingdom over Israel for ever.11 Now, my son, the Lord be with thee; and prosper thou, and build the house of the Lord thy God, as he hath said of thee.
12 Only the Lord give thee wisdom and understanding, and give thee charge concerning Israel, that thou mayest keep the law of the Lord thy God.
KJV

1 Chron 28:2-10
2 Then David the king stood up upon his feet, and said, Hear me, my brethren, and my people: As for me, I had in mine heart to build an house of rest for the ark of the covenant of the Lord, and for the footstool of our God, and had made ready for the building:
3 But God said unto me, Thou shalt not build an house for my name, because thou hast been a man of war, and hast shed blood.
4 Howbeit the Lord God of Israel chose me before all the house of my father to be king over Israel for ever: for he hath chosen Judah to be the ruler; and of the house of Judah, the house of my father; and among the sons of my father he liked me to make me king over all Israel:
5 And of all my sons, (for the Lord hath given me many sons,) he hath chosen Solomon my son to sit upon the throne of the kingdom of the Lord over Israel.6 And he said unto me, Solomon thy son, he shall build my house and my courts: for I have chosen him to be my son, and I will be his father.
7 Moreover I will establish his kingdom for ever, if he be constant to do my commandments and my judgments, as at this day.8 Now therefore in the sight of all Israel the congregation of the Lord, and in the audience of our God, keep and seek for all the commandments of the Lord your God: that ye may possess this good land, and leave it for an inheritance for your children after you for ever.
9 And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the Lord searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.
10 Take heed now; for the Lord hath chosen thee to build an house for the sanctuary: be strong, and
KJV
Ps 2:4-9
4 He that sitteth in the heavens shall laugh: the Lord shall have them in derision.
5 Then shall he speak unto them in his wrath, and vex them in his sore displeasure.
6 Yet have I set my king upon my holy hill of Zion.
7 I will declare the decree: the Lord hath said unto me, Thou art my Son; this day have I begotten thee.
8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.
9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter's vessel.KJV

Hos 11:1
11 When Israel was a child, then I loved him, and called my son out of Egypt.
KJV
Matt 2:13-15
13 And when they were departed, behold, the angel of the Lord appeareth to Joseph in a dream, saying, Arise, and take the young child and his mother, and flee into Egypt, and be thou there until I bring thee word: for Herod will seek the young child to destroy him.
14 When he arose, he took the young child and his mother by night, and departed into Egypt:
15 And was there until the death of Herod: that it might be fulfilled which was spoken of the Lord by the prophet, saying, Out of Egypt have I called my son.KJV
Through Psalm 2 and Matthew 2, we can see that the key is that the Messiah Yeshua` is the Son of God. Matthew 2:15 indicates that Hosea 11:1 is actually talking about the OFFSPRING of Isra'el, rather than Isra'el himself (Ya`aqov or Jacob). There's a telescoping effect that the author of Hebrews gives us in that each subsequent generation is in the seed of the previous generation. (Heb. 7) Thus, just as Leviy paid tithes to Malkhi-Tsedeq through Avraham, being yet in his "loins," so too Yeshua` was called out of Egypt while still in the "loins" of His father Isra'el, or rather the great-great-great-great grandson of Isra'el, Nachshown, who was the leader of the tribe of Y'hudah when they left Egypt!

Now, when did God acknowledge Yeshua` as His own Son? At His baptism!

Matthew 3:1-17
1 In those days came John the Baptist, preaching in the wilderness of Judaea,
2 And saying, Repent ye: for the kingdom of heaven is at hand.
3 For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
4 And the same John had his raiment of camel's hair, and a leathern girdle about his loins; and his meat was locusts and wild honey.
5 Then went out to him Jerusalem, and all Judaea, and all the region round about Jordan,
6 And were baptized of him in Jordan, confessing their sins.
7 But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?
8 Bring forth therefore fruits meet for repentance:
9 And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
10 And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.
11 I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire:
12 Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.
13 Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him.
14 But John forbad him, saying, I have need to be baptized of thee, and comest thou to me?
15 And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him.
16 And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him:
17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.KJV

So, the Davidic Covenant was confirmed by Yeshua` coming to Yochanan the Immerser for His immersion and God's subsequent declaration that He was His "beloved Son."
More to come!

In the Messiah's love,
