MS Vatican, ebr. 456, fol. 2a

Jewish Mysticism
The intention of this treatise is assuredly that one should believe in the essence of the being of God, blessed be he … his hidden being itself, for even though we know that it is absolutely impossible for the human intellect to comprehend the hidden reality of God, blessed be he, since he is incomprehensible by any comprehension apart from himself. By the way of faith that this treatise mentions in the intention of the thirty-two and thirteen names … it is possible for one to believe in the being of his essence … Moreover, faith is above all comprehension of the created intellect for it is hidden, and it is not at all conceivable, signifiable, or imaginable.
