5579. When they had finished the eating of the produce. That this signifies when truths failed, is evident from the signification of "produce," as being truth (see n. 5276, 5280, 5292, 5402); that truth failed is signified by their "finishing the eating of it." Those who are in the spiritual world are sated with things true and good, for these are their food (n. 5576); but when these have served their purpose, they come again into want. This is as with the nourishment of man by material food when this has fulfilled its use, hunger comes on again. The hunger that is a need of spiritual things, in the spiritual world is evening or the twilight of their day; but after it comes daybreak and morning. Thus there are alternations there. They come into that evening or into spiritual hunger, in order that they may feel hungry and long for truths and goods, which yield them more nourishment when they are hungry, just as does material food to one who is famishing. From all this it is evident what is meant by the need of spiritual things when truths failed.
