This is clear from the meaning of 'the kidneys' as the more internal truth of the external or natural man; and from the meaning of 'the fat that is on them' as its good, dealt with above in 10032. The reason why purified truth is what is meant by 'the kidneys' is that the kidneys are organs purifying the blood, 10032, and 'the blood' means truth, 9393, 10026.
