Song of Solomon 8:9 - Ellicott's Commentary On The Whole Bible

If she be a wall. — The wall and door are emblems of chastity and its opposite. The palace of silver some commentators explain by reference to the custom (among the Druses) of wearing an ornament like a horn on the head. But this is unlikely. The metaphors of the wall and door are naturally expanded. If the maiden grows up virtuous and inaccessible to seduction we will build upon her a palace of silver, i.e., we will so provide for her in marriage that from her may spring an illustrious house; but if otherwise, we will enclose her with boards of cedar, i.e., the strongest precautions shall be taken to guard her honour. This passage is one of the strongest arguments for the theory that chaste wedded love is the theme of this book, the poet going on in Song of Solomon 8:10 to put into the heroine’s mouth a protestation of purity; and by which virtuous disposition, even more than by her beauty, she had won her husband’s love: “I have grown up to virtuous womanhood, and I have found favour in his eyes.”
