God in the delivery of the law did purposely use a voice only, because that such a creature as that was not to be expressed by visible lineaments, as if that voice should have said unto the painter as Echo is feigned to do in the Poet:—James Ussher

Si mihi vis similem pingere, pinge sonum.
Vain painter, why does thou essay to limn my face,
If thou wouldst paint my likeness, paint sound.
