Arcana Coelestia # 2166
2166. 'That you may refresh yourselves' means insofar as it is in keeping. This is not so clear from the proximate meaning of these words in the internal sense, though it is nevertheless clear from the whole train of thought. The subject here is Divine perception - that it might draw nearer to the perception possessed by the Lord's human as it was at that time, and that it might bring itself down nearer to His intellectual concepts, by taking on something natural, and also something heavenly or celestial to go with that something natural, insofar as it is in keeping, meant by 'refreshing oneself'. In the proximate sense 'refreshing oneself by means of bread' means being revived, and so enjoying what little of the celestial is in keeping.
Arcana Coelestia # 275
275. Verse 19 With sweat on your brow you will eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you will return.
'Eating bread with sweat on the brow' means strong dislike of what is celestial. 'Returning to the ground from which he was taken' is reverting to the external man, such as he was before regeneration took place. 'He was dust and would return to dust' means that he was condemned and hellish.
