THE ANTEDILUVIAN WORLD IN TIMES OF NOAH WAS DESTROYED BY THE FLOOD DUE TO WIDESPREAD IMMORALITY AND CORRUPTION AT ALL LEVELS, WHICH INCLUDED ABORTION, EATING EMBRYO’S BLOOD, CANNIBALISM, BESTIALISM, HOMOSEXUALITY, ETC.

RIGHT AFTER THE FLOOD IN GENESIS CHAPTER 9 (9 MONTHS PREGNANCY) GOD BLESSED NOAH AND HIS SONS AND COMMANDED THEM TO “BE FRUITFUL AND MULTIPLY”. He prohibited people to eat blood and in verse 6, GOD prohibits abortion.

Genesis 9:6 (Verse 6, the number of man for he was created at the end of the sixth day. This verse is made up by 12 words composed of 2 phrases of 6 words each = 266 [266 days is the actual pregnancy duration counting since fertilization] summing up 40 letters, the traditional 40 weeks pregnancy from the start of the last menstrual period, known as the gestational age.) 12 also means completion, fulfillment. Adding the numeric value contained by ALL 40 letters in verse 6 we obtain 2,085. The digital root (value obtained by summing digits to compute a digit sum until a single-digit number is reached) is 6. Even more, the first 6 words or phrase value = 981=18=9, the second phrase of 6 words=1,104=6. The first 6 words’ subject is “shedding of blood” and its root value equals 9 which is the term of pregnancy and the second phrase root value is 6, where it speaks about “man being made at God’s image”. [The Hebrew numeral system uses the letters of the alphabet to represent numbers, that is, each consonant or letter has its numerical value.]

Let’s remember that Hebrew is read from right to left. It literally says translating to English: “"Whoso sheddeth the blood of man within man shall his blood be shed for in the image of God made he man”. (Translating this verse by context, “Whoever sheds blood of a person within a person, his blood shall be shed for in the image of God made he the human beings.” What is a person that is in a person? You must say: This is a fetus that is in its mother’s womb. (So, the person performing the abortion should die or have his blood shed too.)

According to Strong’s Hebrew dictionary, H120 íãà'adam (aw-dawm') From H119; ruddy, that is, a human being (an individual or the species, mankind, etc.): - person.

So, the King James Version’s translation is not accurate enough. "Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man." (KJV) However, we can assert that the early pregnancy termination or abortion when is within the first two months or 8 weeks, the embryonic stage, it resembles "shedding of blood"; opposed to this bloodshed is the reason for not doing it, "for in the image of God made he man".

Even the Rabbis understand this and they say Feticide (killing of the fetus) “is expressly forbidden under the statutes of the Noachide Code, derived from the wording of Genesis 9:6. “Accordingly, a descendant of Noah is liable for killing a fetus.”
You can find this in https://www.sefaria.org/sheets/279772?lang=bi Now I reproduce a portion of that page.

It is stated in that book of Aggadot that the Sages said in the name of Rabbi Yishmael: A descendant of Noah is executed even for killing fetuses. The Gemara asks: What is the reason for the opinion of Rabbi Yishmael? The Gemara answers: It is derived from that which is written: “One who sheds the blood of a person, by a person [ba’adam] his blood shall be shed” (Genesis 9:6). The word ba’adam literally means: In a person, and is interpreted homiletically: What is a person that is in a person? You must say: This is a fetus that is in its mother’s womb. Accordingly, a descendant of Noah is liable for killing a fetus.

Contemporary Halakhic Problems, Vol I, Part II, CHAPTER XV Abortion in Halakhic Literature 10 An offense not entailing statutory punishment is certainly not an anomaly. Many such prohibitions are known to be biblical in nature. Others are recognized as having been promulgated by the Sages in order to create a "fence" around the Torah or in order formally to prohibit conduct which could not be countenanced on ethical grounds. Under which category is the prohibition against feticide to be subsumed? Is this offense biblical or rabbinic in nature? At least three diverse lines of reasoning have been employed in establishing the biblical nature of the offense. Rabbi Chaim Ozer Grodzinski demonstrates that the remarks of Tosafot, taken in context, clearly indicate a biblical proscription rather than a rabbinic edict. Feticide, as Tosafot notes, is expressly forbidden under the statutes of the Noachide Code. The Noachide prohibition is derived by R. Ishmael (Sanhedrin 57b) from the wording of Genesis 9:6. Rendering this verse as "Whoso sheddeth the blood of man, within man shall his blood be shed" rather than "Whoso sheddeth the blood of man, by man [i.e., through a human court] shall his blood be shed." R. Ishmael queries, "Who is a man within a man? … A fetus within the womb of the mother." Tosafot deduces that this practice is prohibited to Jews as well by virtue of the talmudic principle, "Is there anything which is forbidden to a Noachide yet permitted to a Jew?" Application of this principle clearly establishes a biblical prohibition.

Verse 7 continues this thread by elaborating on what was said in verse 6: instead of shedding the blood of the person in the person, be fruitful and have children.
That is, do not abort, have children. The two verses complement each other and make the meaning clear.

Additional proof of this is found in Psa 139:16 “Your eyes saw my embryo; and in Your book all my members were written, the days they were formed, and not one was among them.” KJV.
