The Soul, the Aeolian Body, Death, the Mistranslation of the Word Spirit, the Identity of the Airflow of God

When God brought the woman he had just formed to Adam,

So the man gave names to all the livestock, the birds in the sky and all the wild animals. But for Adam no suitable helper was found. (Genesis 2:20 [NIV])

Then Yehovah God made a woman from the rib he had taken out of the man, and he brought her to the man. (Genesis 2:22 [MODIFIED-NIV])

He then became married to his wife, hence,

That is why a man leaves his father and mother and is united to his wife, and they become one flesh. Adam and his wife were both naked, and they felt no shame. (Genesis 2:24-25 [NIV])

And God blessed them,

God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.” (Genesis 1:28 [NIV])

In which case, the intention of God in joining them together in marriage was not just so that the woman could help Adam rule over the earth,

Then God said, “Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.”  (Genesis 1:26 [NASB])

So God created mankind in his own image, in the image of God he created them; male and female he created them.
(Genesis 1:27 [NIV])

Yehovah God said, “It is not good for the man to be alone. I will make a helper suitable for him.” (Genesis 2:18 [MODIFIED-NIV])

But to also have children, hence,

Did he not make them one? And the vestige of the airflow remains in him. And why did he make them one? He was seeking godly offspring. So guard your airflow, and don’t be unfaithful to the wife of your youth. (Malachi 2:15 [MODIFIED-ISV])

In which case, the blessing of “be fruitful and multiply” relates to why children are a reward from God,

Behold, children are a heritage from Yehovah, the fruit of the womb a reward. (Psalm 127:3 [MODIFIED-ESV])

Because when a man has sexual relations with his wife, which is how “be fruitful” is fulfilled,

And Adam knew Eve his wife; and she conceived… (Genesis 4:1 [KJV])

God is then the one who yields offspring as a “reward”, since he is the one that opens or closes the womb,

and bare Cain, and said, I have gotten a man from Yehovah. (Genesis 4:1 [MODIFIED-KJV])

Shall I bring to the point of birth and not cause to bring forth?” says Yehovah; “shall I, who cause to bring forth, shut the womb?” says your God. (Isaiah 66:9 [MODIFIED-ESV])

As such, regardless of whether God yields offspring or not, even if the wife is infertile or beyond her years to conceive, for every sexual act, it is the obligation of a man to always discharge inside his wife, which is why Onan sinned when he discharged outside his sister-in-law,

And Onan knowing that the seed will not be his — that it came to pass whenever he entered to  his brother’s wife, he discharged upon the ground, to not give seed to his brother. And it appeared wicked before God that he did this… (Genesis 38:9-10 [ABP])

Because even though he was at liberty to not perform his Levirate duty all along,

However, if a man does not want to marry his brother’s wife, she shall go to the elders at the town gate and say, “My husband’s brother refuses to carry on his brother’s name in Israel. He will not fulfill the duty of a brother-in-law to me.” (Deuteronomy 25:7 [NIV])

And the Law of Moses does not declare that a brother-in-law is worthy of death for not performing his Levirate duty,

Then the elders of his town shall summon him and talk to him. If he persists in saying, “I do not want to marry her,” his brother’s widow shall go up to him in the presence of the elders, take off one of his sandals, spit in his face and say, “This is what is done to the man who will not build up his brother’s family line.” That man’s line shall be known in Israel as The Family of the Unsandaled. (Deuteronomy 25:8-10 [NIV])

Onan still had sexual relations with his sister-in-law, but prevented conception when he did, in which case, his action then became wicked and worthy of death,

And it appeared wicked before God that he did this; and he put to death also this one. (Genesis 38:10 [ABP])

Because all sexual relations must be done with a husband always discharging inside his wife. As such, not only does the law reveal the right manner in which sexual relations must be done, but also when sexual relations are forbidden, which is during a wife’s menstruation for seven days,

You shall not approach a woman to uncover her nakedness while she is in her menstrual uncleanness. (Leviticus 18:19 [ESV])

If a man lies with a woman during her menstrual period and uncovers her nakedness, he has made naked her fountain, and she has uncovered the fountain of her blood. Both of them shall be cut off from among their people. (Leviticus 20:18 [ESV])

When a woman has a discharge, and the discharge in her body is blood, she shall be in her menstrual impurity for seven days, and whoever touches her shall be unclean until the evening. (Leviticus 15:19 [ESV])

Or within forty days after a wife has given birth to a male child, or within eighty days after she has given birth to a female child,

“Speak to the people of Israel, saying, If a woman conceives and bears a male child, then she shall be unclean seven days. As at the time of her menstruation, she shall be unclean. And on the eighth day the flesh of his foreskin shall be circumcised. Then she shall continue for thirty-three days in the blood of her purifying. She shall not touch anything set-apart, nor come into the set-apart place, until the days of her purifying are completed. But if she bears a female child, then she shall be unclean two weeks, as in her menstruation. And she shall continue in the blood of her purifying for sixty-six days. (Leviticus 12:2-5 [MODIFIED-ESV])

This all relates with keeping the marriage bed undefiled,

Marriage should be honored by all and the marriage bed kept undefiled, for God will judge the sexually immoral and adulterers. (Hebrews 13:4 [BSB])

Because all forms of contraception, masturbation, anal sex, oral sex, sex while a wife is menstruating, or any sexual relations without a husband having vaginal sex and discharging inside his wife as God intended are all forms of sexual immorality that are wicked before God.
