353. By "fat" is signified the celestial itself, which is also of the Lord. The celestial is all that which is of love. Faith also is celestial when it is from love. Charity is the celestial. All the good of charity is the celestial. All these were represented by the various kinds of fat in the sacrifices, and distinctively by that which covered the liver, or the caul; by the fat upon the kidneys; by the fat covering the intestines, and upon the intestines; which were holy, and were offered up as burnt-offerings upon the altar (Exod. 29:13, 22; Lev. 3:3, 4, 14; 4:8-9, 19, 26, 31, 35; 8:16, 25). They were therefore called the "bread of the offering by fire for a rest unto Jehovah" (Lev. 3:14, 16). For the same reason the Jewish people were forbidden to eat any of the fat of the beasts by what is called "a perpetual statute throughout your generations" (Lev. 3:17; 7:23, 25). This was because that church was such that it did not even acknowledge internal, much less celestial things.
 That "fat" signifies celestial things, and the goods of charity, is evident in the Prophets; as in Isaiah:
Wherefore do ye weigh silver for that which is not bread? and your labor for that which satisfieth not? Attend ye diligently unto Me, and eat ye that which is good, and let your soul delight itself in fatness (Isa. 55:2).
And in Jeremiah:
I will fill the soul of the priests with fatness, and My people shall be satiated with My good (Jer. 31:14),
where it is very evident that fatness is not meant, but celestial spiritual good. So in David:
They are filled with the fatness of Thy house, and Thou makest them drink of the river of Thy deliciousnesses. For with Thee is the fountain of lives; in Thy light we see light (Ps. 36:8-9).Here "fatness" and the "fountain of lives" signify the celestial, which is of love; and the "river of deliciousnesses" and "light" the spiritual, which is of faith from love. Again in David:
My soul shall be satiated with marrow and fatness, and my mouth shall praise Thee with lips of songs (Ps. 63:5),
where in like manner "fat" denotes the celestial, and "lips of songs" the spiritual. That it is what is celestial is very evident, because it will satiate the soul. For the same reason the first fruits, which were the firstborn of the earth, are called "fat" (Num. 18:12).
 As celestial things are of innumerable genera, and still more innumerable species, they are described in general in the song which Moses recited before the people:
Butter of kine, and milk of the flock, with fat of lambs and of rams, the sons of Bashan, and of goats, with the fat of the kidneys of wheat; and thou shalt drink the blood of the grape, unmixed (Deut. 32:14).
It is impossible for anyone to know the signification of these expressions except from the internal sense. Without the internal sense, such expressions as the "butter of kine" the "milk of sheep" the "fat of lambs" the "fat of rams and goats" the "sons of Bashan" the "fat of the kidneys of wheat" and the "blood of the grape" would be words and nothing more, and yet they all and each signify genera and species of celestial things.
