Philo Judaeus De Mutatione Nominum 13

[13] For these men have need of the complete use of the divine name who come to a created or mortal generation, in order that, if they cannot attain to the best thing, they may at least arrive at the best possible name, and arrange themselves in accordance with that; and the sacred oracle which is delivered as from the mouth of the Ruler of the universe, speaks of the proper name of God never having been revealed to any one, when God is represented as saying, "For I have not shown them my name;" ¹ for by a slight change in the figure of speech here used, the meaning of what is said would be something of this kind: "My proper name I have not revealed to them," but only that which is commonly used, though with some misapplication, because of the reasons above-mentioned.
