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.

4617. 'A hundred and eighty years' means the nature of this state. This becomes clear from the fact that all numbers in the Word have spiritual realities as their meaning, see 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495. 'A hundred and eighty years' accordingly means the nature of the reality, that is, of the state, which is being dealt with. 'A hundred' means a complete state, see 2636, and 'eighty' temptations, 1963, here by means of temptations - in addition to many other things which cannot be known. Numbers obtain their meanings from the simpler numbers of which they are the products when the simpler are brought together or multiplied, as with the number here which is the product of twelve and fifteen and also of others yet simpler than these.
