ISAIAH 61:1 The Spirit of the Sovereign Lord is on me, because the Lord has anointed me to proclaim good news to the poor. He has sent me to bind up the brokenhearted, to proclaim freedom for the captive and release from darkness for the prisoners. 2 to proclaim the year of the Lord’s favor [snip]
As with much of Gods Word, there are layers of meanings. There is the superficial meaning - face value. That is, the literal meaning. This is well covered in another response.
But there are also ‘deeper’ meanings. Ones that need to be uncovered. But, these often require a foundation, one that cannot be fully explained‘on one page’. Follows is an overview, a summary...
“good news to the poor.” - who are the poor? “poor in spirit” (Mat 5:3). When Adam ‘ate’, his ‘spirit’ died. Jesus came to ‘rectify’ this. And what happened when Adam ‘ate’ ...
GENESIS 3: 7 Then the eyes of both of them were opened
Now again, you need a foundation. This did not mean they were ‘blind’. It means they ‘lost’ the use of their spiritual ‘eyes’ - because their ‘spirit’ instantly ‘died’ when they ‘ate’. And again, Jesus came to ‘rectify’ this. So we have that he came to “recovery of sight for the blind”.
This explains the multiple times the Bible talks about ‘seeing but see not’, and so on ...
MAT 13:13 Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. 14 And in them the prophecy of Isaiah is fulfilled, which says: ‘Hearing you will hear and shall not understand, And seeing you will see and not perceive;
To ‘perceive’, means to ‘understand’ in your ‘heart’ [spirit]. Your ‘spirit’ has both ‘eyes’ and ‘ears’ - and it’s these that need to hear the Word.
Other parts of the verses you are querying also have ‘deeper’ meanings. One issue with ‘deeper’ meanings is that not all will accept these. Exactly what Jesus says many times. Essentially saying ... “[sigh] you just don’t get it”.
The reference to “freedom for the prisoners”. Prisoners to what? The Jews were ‘captive’ to the Law. Bound by the Law. And again, Jesus came to free them from that captivity - by fulfilling the Law for them.
These deeper meanings are not always obvious, and not even always accepted. You will need to consider whether you want to. There are other responses to consider.
