Thy neck is like the tower of David— Thy neck is like the tower of David, built upon an eminence. This tower of David was probably remarkable for the elegance and nice proportion of its structure. This is Houbigant's interpretation. But some render the clause, built with battlements, or running up into spires. See Michaelis and the New Translation.
