Philo Judaeus Quod Deterius Potiori Insidiari Soleat 57

I think, therefore, that enough has been now said with respect to those who appear to think that they do others good or harm. For it has been shown, that that which they think that they are doing to others, they in either case do to themselves. We will now examine the remainder of this event; the question is as follows:—"Where is Abel, thy brother?" ¹ To which answer is made, "I do not know; am I my brother’s keeper?" It is therefore worth while to consider the question whether it can be appropriately said of God that he asks a question. For he who asks a question or puts an inquiry is asking or inquiring about something of which he is ignorant; seeking an answer through which he will know what he as yet does not know. But everything is known to God, not only all that is present, and all that is past, but also all that is to come.
