Plants in the Bible generally represent facts, knowledge that can be gleaned from the world. Plants that can serve animals as food represent facts that have the potential to be put to use, ones that can lead to something good. A pasture, then, is an area that offers a great deal of this sort of useful, life-building knowledge. "Pasture" is often used as a verb in the Bible as well; to pasture animals means teaching people facts that can help them do what is good in life.

9946. 'And for Aaron's sons' means Divine Truths emanating in the heavens from the Lord's Divine Good. This is clear from the representation of 'Aaron's sons' as Divine Truths emanating from the Lord's Divine Good, dealt with in 9807, in the heavens being meant because that which is Divine and the Lord's in the heavens is what the priestly office of Aaron and his sons represents. Divine Good in the heavens is represented by Aaron's priestly office, and Divine Truth from Divine Good there by that of his sons. The words 'in the heavens' are used because the Lord Himself, being the Sun of heaven, is above the heavens, yet has a presence within the heavens, which is such that it seems as though He Himself were there. The Lord as He is in the heavens - that is, His Divine Good and Divine Truth there - is able to be represented, but not that which is Divine and His above the heavens, because this cannot fall within the range of what human minds or even angelic minds can grasp, since it is infinite. But what is Divine and emanates from it into the heavens is suited to reception there.
