Ṣelem means image or likeness — a representation that corresponds to and reflects an original. Its most theologically concentrated appearances are in Genesis 1:26-27 and 9:6, where it describes the human being as created in God's image (bəṣelem ʾĕlōhîm). The word is also used for idols, for the shadow-image of human transience in the Psalms, and for the carved images of pagan gods.
Understanding what Genesis means by ṣelem requires attention to the ancient Near Eastern background: in the cultures surrounding Israel, a ṣelem was the representative statue of a king or god placed in a territory to signal sovereignty and presence. The king's image in a province declared whose reign extended there. When Genesis declares that God made humanity in his ṣelem, it is claiming that human beings — all of them, not only kings — are God's representative presence in the creation.
They are placed in the world to display who rules it. This reading does not require that the image is a quality humans possess (reason, morality, relationality) but that it is a role or function they occupy: to reflect God's character and represent his reign in the created order. The fall in Genesis 3 does not erase the image (Gen. 9. 6 still cites it as the ground of prohibiting murder), but it distorts the function.
The New Testament's account of Christ as the image of God (Col. 1. 15, Heb. 1. 3) and of believers being transformed into the same image (2 Cor. 3. 18) is the restoration of what the fall disrupted.
