Bonaventure, on Gen 15:5

“And he brought him forth abroad, and said to him: Look up to heaven and number the stars, if thou canst. And he said to him: So shall thy seed be.”

“We have spoken of the second vision, that is, of understanding lifted up by faith, as expressed through the words "heaven," or "firmament," meaning lofty, firm, and beautiful. Of this, it was said to Abraham, that is, to the believer: "Look at the heavens and, if you can, count the stars." And by the twelve signs through which the sun of understanding runs as it traverses the hemisphere of our intelligence, producing the day and the year of faith; and by the twelve gates, each one made of a single pearl, may be understood the twelve principal ideas to which the others may then be retraced, and according to which the others are ruled and directed: and these twelve principal ideas are bright, vivifying, and joyful. The first of these ideas was to consider God as the first Being; the second, to consider Him as triune.”
