In the Bible it seems this is the first and only time that Abel and Cain made an offering to God since Cain becomes angry that his sacrifice was not respected and he hated Abel for being good, and therefore he slays Abel.
'if you do well' also gives the tacit indication that Cain knew what was supposed to be done, but wasn't doing it. this implies either previous instruction in the process or previous experience or both.
The chapter opens up with Eve bearing Cain and then bearing Abel. So, "in the process of time" means that they grew up from babies into men.
it is an interesting phrase, literally, "at the end of days" -- as though there was a set time, and they had waited for it, and then proceeded it.
time on earth is cyclical; God appointed the sun and moon as clocks for us to keep and observe time, and they are cyclical. the mention of a time occurring 'at the end of days' indicates that there was an accounting of days, and an accounting of days in a cyclically measured timespan.. well, you know -- just like the Mosaic law, the feasts occur yearly, on appointed days.
just a coincidence?
This chapter comes after Genesis 3 because this is simply what happened next. The only connection with Genesis 3 is at the beginning of chapter 4, detailing how Adam and Eve begat Cain and then Abel. Genesis as a book tells us about the Beginnings of everything, hence the title. A lot of firsts in the book of Genesis and it will set the foundation for the entire rest of both the Bible as a book and the reality that we live in today.
does Genesis seem like simply a documentary of sequential disconnected events to you?
none of this stuff is in any way related?
is that typical of God's book?
hmm.
