Well, Saints Paul, Matthew, Luke, John, Peter and John the Baptist all refer to the start of Daniel’s seventieth week. As for a reference to the entirety of the seventy weeks, we can point to how Jesus alludes to the Seventy Weeks in cryptic language.
The verse I am thinking of is when Peter asked Jesus how often should he forgive, then suggested what he thought was generous "Up to seven times," he posits.
"Then Peter came to Him and said, “Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?” Jesus said to him, “I do not say to you, up to seven times, but up to seventy times seven." (Matthew 18:21-22)
Jesus answer was cryptic, but I think he was referring to the long era of forgiveness 490 years that God was giving his people Israel until he introduced his New Covenant. In other words, if it was good enough for God to wait seventy times seven, it is good enough for us to forgive seventy times seven too.
Surely Jesus had Daniel in mind when he made that statement.
But we are to forgive people more than 70 times 7. Jesus 70 times 7 was different from Daniels because Daniels was a times table. Jesus was answering the question of are we to forgive 7 times thus Jesus was using the 7 to show an unlimited number.
Which verses were you referring to which the people you mentioned?
Mathew would of confirmed Jesus fulfilling them like he did with other prophecies Jesus fulfilled like he did here in the examples below
22 All this took place to fulfill what the Lord had said through the prophet: 23 “The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”).
5 “In Bethlehem in Judea,” they replied, “for this is what the prophet has written:
6 “‘But you, Bethlehem, in the land of Judah,
are by no means least among the rulers of Judah;
for out of you will come a ruler
who will shepherd my people Israel.’”
14 So he got up, took the child and his mother during the night and left for Egypt, 15 where he stayed until the death of Herod. And so was fulfilled what the Lord had said through the prophet: “Out of Egypt I called my son.”
3 In those days John the Baptist came, preaching in the wilderness of Judea 2 and saying, “Repent, for the kingdom of heaven has come near.” 3 This is he who was spoken of through the prophet Isaiah:
“A voice of one calling in the wilderness,
‘Prepare the way for the Lord,
make straight paths for him.’”
12 When Jesus heard that John had been put in prison, he withdrew to Galilee. 13 Leaving Nazareth, he went and lived in Capernaum, which was by the lake in the area of Zebulun and Naphtali— 14 to fulfill what was said through the prophet Isaiah:
15 “Land of Zebulun and land of Naphtali,
the Way of the Sea, beyond the Jordan,
Galilee of the Gentiles—
16 the people living in darkness
have seen a great light;
on those living in the land of the shadow of death
a light has dawned.”
17 From that time on Jesus began to preach, “Repent, for the kingdom of heaven has come near.”
There are many more examples from Matthew and did you see that at times Matthew quoted which prophet said these verses?
Not once did Mathew or any NT writer or even Jesus Himself state that Jesus fulfilled any of the 70 weeks.
How about my other two points showing that the 70 weeks were to the Jews before the cross?
