Please read Genesis chapter 9.
There are several covenants in the Old Testament. Those commandments given to Adam and to Abel also apply to the survivors
of the Flood. The covenant God made with Noah is called the Noahide Covenant. It applies to the children of Noah, you and
me. This covenant emphasizes continued obligation to obey the pre-flood commandments, and introduces only a handful of new
Abel and Cain knew God's desired sacrifice. Cain did not obey. Both were free to disobey. Genesis 4:4-5 "... and
Abel brought of the firstlings of his flock.. but to Cain and to his offering HE(God) did not have respect."
What did God respect? God had asked for the firstfruit. I use deductive reasoning with LOGIC. Cain's offering was not
a firstfruit and Abel's was.
Genesis 7:2-3 "of every clean beast you are to take sevens,..."
The Noahide covenant was ratified by sacrificial offerings of clean animals. Without the shedding of blood, there is no
covenant. Noah knew which animals were clean and which were unclean. Noah had 7 pairs of clean animals in the Ark, but the
unclean animals were only 1 pair each. God had taught Adam's sons the difference between clean and unclean. Gen 8:20 "and
Noah built an altar to YHWH, and took of every clean animal and clean bird and offered burnt offerings on the altar."
Some instructions must be deduced through intense Bible Study. When did God talk to Abel about sacrifices?
When did God tell Noah what kind of animal was clean or not? If the Bible were to expound on all conversation between
God and man, the Bible would be 10,000 pages long. Through Bible study we can learn all the blessings God offers. Some are
Noah and co. sacrificed CLEAN animals. Sacrifices legalize convenants, and legitimize past covenants.
Genesis 2:2-3 God rested on the 7th day and sanctified it. We should be holy as God is holy. Just as the Bible would be
redundant to include God telling Abel he wanted the firstfruit sacrifice, it would have been redundant for the Bible to include
God telling Adam to observe the Sabbath.
It is obvious... what God sanctifies, Adam would also sanctify. It is sheer logic. Adam observed the Sabbath.
Noah was "righteous in the sight of YHWH" because he was obedient. He observed the Sabbath.
The very first commandment to humans given in the Bible is to "Be fruitful and multiply" Gen 1:28. The paramount
commandment. It even supercedes most other orders, it is as a Trekkie would say... the prime directive. "Be fruitful"
means, bear good fruit, be quality people, be obedient. It does not mean you must raise children, whether you can afford to
have children or not. "Multiply", is instruction to have Godly children, ONLY if married and one can afford children.
But Adam and Eve eloped, they did not get married! When they had sex, that ceremony ratified their marriage.
When did God tell them that children had to be born in wedlock? The Bible does not say. But rest assured, they knew.
Noah and children were told "be fruitful and multiply" Gen 9:1. Why weren't they told to observe the sabbath?
I don't know. But I think it's because they didn't have to be told, since they already observed the Sabbath. God considered
Noah as righteous for a reason, and that reason had to be that Noah observed the Sabbath and did not murder or fornicate.
Notice that Noah probably feared having sons after Ham, since mankind was utterly corrupted. Notice also that neither
son of Noah had any children, yet all were married at least 1 year before the Flood, when God first announced the Flood plans.
This is exceedingly strange for 3 married couples to not have children. 8 people were allowed on the Ark. It is extremely
strange that Noah not have more than 3 children, God had blessed him, he could have had more children. It is extremely strange
that his married children, had no children of their own. All this is circumstancial evidence that Noah and his children refused
to have any more children, or maybe were told by God to cease multiplying temporarily. They had to be coerced to pro-create
after the flood. God had to bless them, and re issue the prime directive to them after the flood. Be fruitful and multiply.
We must be holy and loving and make new believers out of heathens.
By the way...
No creature with gills were allowed on the Ark, they don't have breath of life that land animals breathe. Fish were not
corrupted like animals were. By the way, fish never have to be killed in a kosher manner like animals do. All fish with fins
and scales are automatically clean food.
The following is logical conjecture. Some sea species were lost due to the flood. Due to massive dirt drainage into the
specific ocean areas, clogged gills couldn't breathe. Some land species did not multiply successfully after the flood and
those species have gone extinct. It was a commandment, it was a choice to pro-create or not.
