Hello TM19782017, the Septuagint is the only OT translation (Hebrew into Koine Greek) that existed at that time (that I know of).
As for Jesus referencing the Scriptures,
@posthuman had it right when he said, "
like, almost always". Here are a few examples of Him doing so.
Matthew 4
1 Jesus was led up by the Spirit into the wilderness to be tempted by the devil.
2 And after He had fasted forty days and forty nights, He then became hungry.
3 And the tempter came and said to Him, “If You are the Son of God, command that these stones become bread.”
4 But He answered and said, “It is written, ‘MAN SHALL NOT LIVE ON BREAD ALONE, BUT ON EVERY WORD THAT PROCEEDS OUT OF THE MOUTH OF GOD.’ ”
5 Then the devil took Him into the holy city and had Him stand on the pinnacle of the temple,
6 and said to Him, “If You are the Son of God, throw Yourself down; for it is written,
‘HE WILL COMMAND HIS ANGELS CONCERNING YOU’;
and
‘ON their HANDS THEY WILL BEAR YOU UP,
SO THAT YOU WILL NOT STRIKE YOUR FOOT AGAINST A STONE.’ ”
7 Jesus said to him, “On the other hand, it is written, ‘YOU SHALL NOT PUT THE LORD YOUR GOD TO THE TEST.’ ”
8 Again, the devil took Him to a very high mountain and showed Him all the kingdoms of the world and their glory;
9 and he said to Him, “All these things I will give You, if You fall down and worship me.”
10 Then Jesus said to him, “Go, Satan! For it is written, ‘YOU SHALL WORSHIP THE LORD YOUR GOD, AND SERVE HIM ONLY.’ ”
11 Then the devil left Him; and behold, angels came and began to minister to Him.
Mark 7
1 The Pharisees and some of the scribes gathered around Him when they had come from Jerusalem,
2 and had seen that some of His disciples were eating their bread with impure hands, that is, unwashed.
3 (For the Pharisees and all the Jews do not eat unless they carefully wash their hands, thus observing the traditions of the elders;
4 and when they come from the market place, they do not eat unless they cleanse themselves; and there are many other things which they have received in order to observe, such as the washing of cups and pitchers and copper pots.)
5 The Pharisees and the scribes *asked Him, “Why do Your disciples not walk according to the tradition of the elders, but eat their bread with impure hands?”
6 And He said to them, “Rightly did Isaiah prophesy of you hypocrites, as it is written:
‘THIS PEOPLE HONORS ME WITH THEIR LIPS,
BUT THEIR HEART IS FAR AWAY FROM ME.
7 ‘BUT IN VAIN DO THEY WORSHIP ME,
TEACHING AS DOCTRINES THE PRECEPTS OF MEN.’
8 “Neglecting the commandment of God, you hold to the tradition of men.”
9 He was also saying to them, “You are experts at setting aside the commandment of God in order to keep your tradition.
10 “For Moses said, ‘HONOR YOUR FATHER AND YOUR MOTHER’; and, ‘HE WHO SPEAKS EVIL OF FATHER OR MOTHER, IS TO BE PUT TO DEATH’;
11 but you say, ‘If a man says to his father or his mother, whatever I have that would help you is Corban (that is to say, given to God),’
12 you no longer permit him to do anything for his father or his mother;
13 thus invalidating the word of God by your tradition which you have handed down; and you do many things such as that.”
Luke 19
45 Jesus entered the temple and began to drive out those who were selling,
46 saying to them, “It is written, ‘AND MY HOUSE SHALL BE A HOUSE OF PRAYER,’ but you have made it a ROBBERS’ DEN.”
47 And He was teaching daily in the temple; but the chief priests and the scribes and the leading men among the people were trying to destroy Him,
48 and they could not find anything that they might do, for all the people were hanging on to every word He said.
John 5
45 “Do not think that I will accuse you before the Father; the one who accuses you is Moses, in whom you have set your hope.
46 “For if you believed Moses, you would believe Me, for he wrote about Me.
47 “But if you do not believe his writings, how will you believe My words?”
