I had an idea about Job. In Job 38:21, the Deity seemed to call Job a very old person, as if Job was born a very long time ago. The statement seems not to be a question. And the Deity probably wasn't being sarcastic, because He tells the truth. His words are truth (~Psalm 119:160, Psalm 19:7, Psalm 119:89, John 17:17, 2 Samuel 7:28). Besides, it would confuse people if He was sarcastic, if He said the opposite of what He meant. So Job was very very old. But, how can he be so old (Job 38:21), if he was recorded to only have lived so many years before dying (Job 42:16-17)? Maybe this is a case of some sort of reincarnation.
Reincarnation, at least for some people and to some extent, has some biblical credit. Malachi 4:5 says that Elijah the prophet would be sent, and that was after he was taken up into heaven. Christ identified John the Baptist as Elijah, and there was an account of John the Baptist being born to Elizabeth. So, reincarnation seems to be biblical. Malachi 4:5 did not say a person like Elijah. It seems to say Elijah himself. John the Baptist denied that he was, but Christ said that John the Baptist was Elijah, and Christ's words trump John's. And John could have forgotten or not yet gained remembrance of his past life or lives. Apparently, in Buddhism, reincarnation is an accepted concept, and people can remember their past lives and even perceive the past lives of others, but only after attaining specific criteria of "Enlightenment". So maybe Christ had these abilities, to see others' past lives, but John had not gained those abilities because he didn't get to that Enlightenment. Maybe that is why Christ told his disciples that they had been with him from "arches" (Greek, John 15:27).
And Christ not only seemed to say that John the Baptist was Elijah, but Elijah who was about to come. And this was said after John was put in prison and about to die. So, maybe Christ was speaking of another time at which Elijah would come, perhaps by reincarnation.
The "Song of Moses" taught by Moses to the Israelites, was passed on from generation to generation as a kind of spiritual inheritance. So it seems that at least, there is an ability for some spiritual inheritance to be "reincarnated" in a sort of way, that way (Deuteronomy 32:21).
In Genesis 1:26, humans are supposed to rule in a fish, and in a flying thing, and in a creeping thing, and in all of the earth. So maybe that passage is describing some amount of coe that is literally inside those creatures that reincarnates to become human. Also, the Hebrew word written there for "ruling over" can also possibly mean "to scrape" or "to scrape out", as in a scenario of Samson scraping out honey from inside a carcass of a lion. So, maybe humans can scrape out coe from inside other creatures and add it to their own, which would be reincarnation for that "scraped out" coe, as it goes out of one body and into another, to some extent.
So, perhaps Job too was reincarnated, and that's how he could have been so old, even if his physical body lived and died within hundreds of years.
So, what if Job was born on "Day Zero" of creation? If he was really old, and he was talking about his birth, then could he have been talking about "Day Zero" in Job 3? Like before light was called into existence? Job 3:6 shows that Job didn't want the day of his birth to be counted with other days, like it would be outside of the calendar. And he wanted that day to become (a) darkness, similar to what it might have been like before light was called on Day 1 of Genesis.
If that is the case, then it is interesting that Leviathan (or Luythen) is mentioned. It seems to be invoked like a protector of that day of Job's (past life's) birth. It is interesting Job seems to be using Leviathan as a protector for that day. And if the day that it is protecting is "Day Zero" (coming before Day 1 of Genesis), then it is protecting against people trying to gain any perception of what happened before Day 1 of Genesis? And Leviathan is mentioned again by the Deity in Job 41. It describes Leviathan and maybe gives insight on how to defeat it.
Since "out of the over-abundance/overflowing of the heart, the mouth speaks", and the Deity's words began Day 1 of Genesis and ended "Day Zero", the overflow/abundance of the heart of the Deity may have been related to His defeating of the "enemies of Day Zero" like darkness, things staying the same, etc.. Leviathan may have been a "heart-enemy" that was defeated in order to end "Day 0" and bring about light from the call for light from the abundance or overflow of the heart of the Deity. Perhaps each person also has some kind of Leviathan-esque "heart enemy" to defeat in order to become pure of heart?
I use the term "heart-enemy" because I had another idea about "Day Zero". I was reading Joshua 6:26. It reminded me of the Father sending his Son. Creation was made through the Son (John 1:1-3), and Christ is called the foundation or cornerstone (1 Corinthians 3:11, Ephesians 2:20, Acts 4:11, Psalm 118:32 and Matthew 21:42 and Mark 9:12). So it seemed like Jericho, in the book of Joshua, might represent a city of "enemies of Day Zero" because it was said that whoever rebuilds that city lays the foundation in his firstborn. And the Christ is the firstborn (Psalm 89:27, Colossians 1:15-17). And Christ apparently may also be the last born (Revelation 22:13), so the other part of Joshua 6:26 might apply to Christ too. In fact, the whole book of Joshua seems to me like it may be describing, to some extent, also some kinds of enemies and how they can be / were defeated that were overcome in order for creation in Genesis to happen.
Also, Joshua in Hebrew, may be exactly the same pronunciation as Jesus' name in Hebrew. The Israelites crossed a river to a new place that the Deity had promised to give to them. A leader figure with a similar or same name as the first born of creation, led those chosen by the Deity to defeat enemies and inherit their place. Doesn't it sound like it could also be describing creation in Genesis?
These are some ideas I had. Let me know what you think of them.
