That's a bit confusing. Adam and Eve were two distinct people. And what do you mean by "Express image"?
In the following passage Elohym creates Adam (masculine form of Adamah lit., Earth) after the 'Image and Likeness' of Elohym, specifying Male and Female, thus he was originally Hermaphrodite (having both sexes) Like his Maker;
"So Elohym created man in his own image, in the image of Elohym created he Him; Male and Female created he Them." [Genesis 1:27]
"And I will cleanse them from all their Iniquity, whereby they have sinned against me; and I will pardon all their Iniquities, whereby they have sinned, and whereby they have transgressed against me." [Jeremiah 33:8]
According to Jeremiah 33:8 'iniquity' is the precursor for Sin, yet literally means 'Perversity' i.e, twisted, to miss apply, miss use, and miss interpret;
The 'Perversity' of Adam that precedes the first Sin is a miss interpretation, for Elohym (the true Life Giver) said, 'I will make Adam a suitable helper', referring to the Spirit (aka wife of one's youth, ref. Malachi 2:15);
After declaring this, Elohym proceeded to bring the animals before him to see what he would call them, yet he thought Elohym had proposed to fashion him a Suitable helper, and that is why he did not find one of them Suitable for him;
The mode of operandi of Elohym when someone is found without the Love for Truth (< אמן a'mən, may also translate 'our mother'), he customarily hands them over to their (unwarranted) fear, (immature) imaginations, or (inappropriate) judgements;
No sooner than Adam's realization was communicated, Elohym (being a Jealous deity) cast Adam into a Deep Sleep (coma), which is (biblically) synonymous with Death, then prepares to hand him over to what he was expecting;
Elohym forms the woman from Adam's rib, and then presents her to him, at which time Adam is no longer A-sexual, yet proudly declares, "this is flesh of my flesh, and bone of my bones..."
The scripture is careful to point out that Adam and the woman were both naked, yet were not ashamed, however (biblically) one's nakedness is supposed to be considered a Shame; (ref. Ex. 32:25)
Immediately upon seeing their lack of shame Satan enters the picture, who (according to 1st Chronicles 21:1 and 2nd Samuel 24:1) represents the Anger of Yah;
Now as was stated, Adam was created in the Image and Likeness of Elohym, and in Webster's third DAE in the third entry for 'Reflection' we find "anything reflected, specif. image; likeness (end of entry)"
Seth aka The Son of Adam (Man) was fashioned "In the Likeness, and After the Image" of Adam (carefully notice the mirror reverse order from "in the Image, and After the Likeness;
Thus, Adam was a reflection of Elohym, and Seth was a Reflection of Adam, circumstantially making Seth the Express (not a mirror opposite reflected) Image of Elohym; (ref. Heb. 1:3 Christ is the Express image)
More than any other title Y'shua proclaimed to be the Son of Adam, and since the days of Noah's flood, Adam has only one begotten son inhabiting the earth, consequently, we (the remnant of Adam) constitute the Many Members of the body of Seth; (ref. 1stCorinth Corinthians 6:15)
This is what was meant by "he has a name written that no man knew but he himself." (Rev. 19:13)
For Y'shua did not come in his own name, but in the name of the Father, and the day before he was crucified he said to his disciples, "Up unto this moment you have asked nothing in my name, Ask..." (John 16:24)
"Male and female created he them; and blessed them, and called their name Adam, in the day when they were created." [Genesis 5:2]
After separating the woman from Adam the concept of marriage became a necessity or we inadvertently might think we are two beings, and not One being, notice how he called them Adam, not Adam and Eve;
