The Hebrew word Adam means “man” or “mankind.”
The use of the Hebrew plural “let us” with the singular verb “make” refers to an early hint of the Trinity.
What does the phrase “image and likeness of God” mean? By adding “likeness,” Moses indicates that this does NOT mean an exact one. Not “a little god,” as heretical charismatics (esp. NAR) teach. Rather, a divinely designed similarity, including an ability to commune with God.
