It's there!

I concluded above that ṣelem and dəmût in Gen 1:26–27 were used to describe the creation of humankind because the author was likening the divine-human relationship to that of father and son. In doing so, he was also redefining ṣelem: the divine is not manifest in a human-made statue. Rather, ṣelem denotes a living human being. A close reading of Gen 2:5–3:24 reveals that, although the terms ṣelem and dəmût are absent, the themes of kinship, kingship, and cult are present in the Eden story, as well.—The "Image of God" in the Garden of Eden, page 138
