[7:4] 1 tn Alternately, “the ivory tower.” The noun הַשֵּׁן (hashshen, “ivory”) is a genitive of composition, that is, a tower made out of ivory. Solomon had previously compared her neck to a tower (Song 4:4). In both cases the most obvious point of comparison has to do with size and shape, that is, her neck was long and symmetrical. Archaeology has never found a tower overlaid with ivory in the ancient Near East and it is doubtful that there ever was such a tower. The point of comparison might simply be that the shape of her neck looks like a tower, while the color and smoothness of her neck was like ivory. Solomon is mixing metaphors: her neck was long and symmetrical like a tower; but also elegant, smooth, and beautiful as ivory. The beauty, elegance, and smoothness of a woman’s neck is commonly compared to ivory in ancient love literature. For example, in a piece of Greek love literature, Anacron compared the beauty of the neck of his beloved Bathyllus to ivory (Ode xxxix 28-29).
