Gospel according to Mark (Quotes from Old Testament)
Mark was not an Apostle; he was a follower (disciple) of Peter (his uncle) who later traveled with Paul and Barnabus. He wrote this Gospel around 70 AD making it one of the earliest written. It appears to be written to all believers and narrates the ministry of Jesus from his baptism by John the Baptist to his death and resurrection. He quotes some scripture but mostly to tell the story of Jesus and his ministry. His writings may or may not have been firsthand accounts but they were inspired by the Holy Ghost.
He quotes hardly any scripture, in fact only three, Malachi, Isaiah, and Psalms: (not including what Jesus quoted)
Mark 1:2-3 Matthew 3:3 Luke 3:4 John 1:23
As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. 3 The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Malachi 3:1 Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the Lord of hosts.
Isaiah 40:3 The voice of him that crieth in the wilderness, Prepare ye the way of the Lord, make straight in the desert a highway for our God.
Mark 11:9 Matthew 21:9 John 12:13 And they that went before, and they that followed, cried, saying, Hosanna; Blessed is he that cometh in the name of the Lord:
Psalms 118:26 Blessed be he that cometh in the name of the Lord: we have blessed you out of the house of the Lord.
Mark 15:28 Luke 22:37
And the scripture was fulfilled, which saith, And he was numbered with the transgressors.
Isaiah 53:12 Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors
