Arcana Coelestia #38
38. Verse 18 And to have dominion over the day and the night, and to make a distinction between the light and the darkness; and God saw that it was good.
'The day' is used to mean good, and 'the night' evil. Consequently goods are called 'the works of the day', whereas evils are called 'the works of the night'. 'The light' is used to mean truth, and 'the darkness' falsity, just as the Lord says,
Men preferred darkness rather than light; he who does the truth comes to the light. John 3:19-21.
Verse 19 And there was evening, and there was morning, a fourth day.
Arcana Coelestia #1166
1166. In the Word 'Put' or Libya means cognitions drawn from the literal sense, which in a similar way confirm false assumptions. 'Put' also means simply such cognitions. This is clear from places quoted already where Cush is referred to. Because Cush too means cognitions, though interior ones, Put and Cush are mentioned together in the Word. Among the places quoted above, see Jeremiah 46:9; Ezekiel 30:4-6; Nahum 3:9; Daniel 11:43.
