Arcana Coelestia # 1084
1084. 'They took a garment' means that they placed a good interpretation on it. This is clear from what has been stated already. 'Taking a garment and covering someone's nakedness' can have no other meaning when 'being uncovered' and 'nakedness' mean errors and perversities.
Three hundred
'Three hundred,' as in Genesis 6:15, signifies remains. In general, 'three hundred' signifies fullness, because the number comes from three and a hundred multiplied. Both 'three' and 'a hundred' signify fullness. The significance of products or sums of numbers is seen in the simple numbers that factor into them.
