Like I said, be careful. You are thoroughly mistaken on this. Compare the original wording of Isaiah 61 with the "quotation" of those same verses Jesus read directly from the Scroll of Isaiah in the temple. He deliberately left out part... right in the middle.
No. I am not mistaken.
Let's look at the passage and compare them line by line.
1. Isaiah 61 says ---> The Spirit of the Lord God is upon me.
Luke 4 says --------> The Spirit of the Lord is upon me.
> Here we see the same meaning conveyed even if the word "God" is left out. For we know the Lord is God (according to Scripture).
2. Isaiah 61 says ------> because the Lord hath anointed me to preach good tidings unto the meek.
Luke 4 says -----------> because he hath anointed me to preach the gospel to the poor.
> Here good tidings is the same as saying good news. The good news is the gospel. In the beattitudes: We learn that those who are blessed are those who are poor in spirit and those who are meek. So the poor here is in reference to those who are poor in spirit which to say the same thing as those who are meek. So they say the same thing.
3. Isaiah 61 says -----------> he hath sent me to bind up the brokenhearted,
Luke 4 says ----------------> he hath sent me to heal the brokenhearted,
> This is saying the same thing. To bind up means to heal. See Psalm 147:3.
4. Isaiah 61 says ------------> to proclaim liberty to the captives,
Luke 4 says -----------------> to preach deliverance to the captives,
> Again, this is saying the same thing. To proclaim liberty and to preach deliverance is saying the same thing.
5. Isaiah 61 says -------------> and the opening of the prison to them that are bound,
Luke 4 says ------------------> and recovering of sight to the blind, to set at liberty them that are bruised,
> Jesus was expounding on Scripture at this point. Sort of like what a Pastor does with a time honored verse in Scripture. See, his audience was not stupid. They knew what the passage said. Jesus was providing more details as to the meaning of what Isaiah 61 was saying and what the Word of God already says elsehwere on the matter. For Psalm 146 gives us more details about setting free the prisoners. It talks about giving sight to the blind and executing judgment upon the oppressed (i.e. those who are bruised). So if one knows about Psalm 146, then Jesus' words are not an addition to God's Word. Jesus was still quoting Scripture. For if I quoted the first half of John 3:16 to you, then I quoted another time honored verse that people know and then finish with John 3:16.... that is not a misquote. It was an intentional back and forth quoting of various Scripture verses.
6. Isaiah 61 says ----> To proclaim the acceptable year of the Lord, (and the day of vengeance of our God, to comfort all that mourn; )
Luke 4 says ---------> To preach the acceptable year of the Lord.
*Then Jesus closed the book*
> This is not an elimination fo Scripture but merely Jesus stopping in his quote of Scripture. For the rest of this verse deals with His return (i.e. His 2nd Coming when He will destroy the nations of this Earth and usher in a new world of peace whereby he will give comfort to those who mourn).
