Thanks for the query. First, your source states that "The English text in this HTML edition of the Hebrew Bible is based on the electronic text (c) by Larry Nelson (P.O. Box 1681, Cathedral City, CA 92234 USA, nelsonlarry@juno.com) as found on the Internet in differing copies." And I do not think it is transliterating the Hebrew precisely into English. For instance, look at how many words it gets out of Job 34:10, "Far be it from God, that He should do wickedness; and from the Almighty, that He should commit iniquity," when literally as seen here , "from" "that he should do" "hat he should commit" is missing, and can easily be understood ass saying, "Far be it from God, wickedness; and from the Almighty, iniquity." May all that is within me always affirm this.
The word for "the" before "the women" was not shown in the KJV text i had with Strong's numbers, but as a result of your query i have found it (and i do not claim to know any language other than English, but thank God we can do research) in this source as defined by Strong's here as "used for all numbers and genders," and which can contextually refer to "the women" in the plural, as in Gen. 14:16.
The enmity in Gn. 3:15 (a rare Hebrew word occurring elsewhere only in Numbers 35:21-22, Ezekiel 25:15; 35:5 and is said to denote the “blood-feud”) is between the devil and the woman Eve as representing all women and her offspring in general, whom the devil seeks to seduce and murder since they are basically made in the image of God.
In rabbinical Judaism, WP documents "the contrasting groups of "seed of the woman" and "seed of the serpent" are generally taken as plural, and the promise "he will bruise your head" applied to Adam / mankind bruising the serpent's head.[1]"
However, while the devil has a basic animosity toward man, even though, like liberals, he presents himself as their savior in order to gain power, yet as regards bruising mankind in general can hardly be said to have bruised the head of devil, except by the Godly. But that "her seed" principally refers to the most important seed of Eve and of the women, Christ, is what is fulfilled prophetically. And thus Paul's specification of "women, in "when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons. (Galatians 4:4,5)
"Seed" (zera, singular noun used singular or collective) being masculine in Hebrew, Eve perhaps was expressing hope that he offspring would reverse the curse in exclaiming, , "I have gotten a man from the LORD." (Gen 4:1).
The Mary was the specific women chosen to be the vessel to bring forth the promised Messiah made her blessed among women, this being a holy desire of such Godly spirit filled holy women, to the glory of God, in contrast to the blasphemous attributions and adulation Catholics give to their manufactured Mary , which the Holy Spirit nowhere gives to any created beings. Those who would defend the unique glory and honor of God according to His wholly inspired word must oppose imaginations and exhalations of men not seen therein, and contrary to it, and thus the obedience which is of Christ. (2 Corinthians 10:5)
