There are:Thanks Psalm 1, for your response. Many people read the Bible as you do, as a surface text without the need to see parable or figurative interpretations. I am different from you in that I see the Bible as being written in parable form. We learn about that in Psalm 78: "Give ear, O my people, to my law: incline your ears to the words of my mouth. I will open my mouth in a parable:" This is a scripture which many do not acknowledge, or they shoo it away as only pertaining to small parts of the Bible. Yet the verse says that it is about God's law, which is the entire Bible. We find this backed up by Mark chapter 4, among other places, where we learn that Jesus did not even speak except in parables: "But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples. " Now that is interesting and is not recognized by many denominations. Not because they are correct, but because they do not receive it. Jesus further explains: "And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables:" Here, Jesus explains that all these things are done in parables, but that the Bible is a parable which those who are without (the unsaved) do not understand. He goes on to explain that those who are saved are given to understand the parable of the Bible. He does this by saying that: "Unto you it is given to know the mystery of the kingdom of God ". That is, unto the true believers. He goes a little further to explain that it is while they are alone with Jesus that he explains his words to them: "and when they were alone, he expounded all things to his disciples. "
The verse you are interested in Rev 20 talks about Satan being bound for a thousand years. That is the time during which Satan can do absolutely nothing to stop people from believing in Jesus unto salvation, once God opens up their ears to hear. Satan is bound in respect to people being able to believe on Jesus and Satan cannot stop them from believing. Satan can't say, sorry you're not allowed to believe. Jesus would save the person despite this. That is why God set an open door, not a closed one, for persons to believe the gospel. Satan is bound. He cannot stop that.
parables
Types and shadows
Riddles
Metaphors
Etc.
Then the literal that is self explanatory.
For example NT salvation only points to that.
No parable there.
The types are in the OT.
THEY pointed to Jesus.
Jesus does not point to them, unless He says it specifically.
