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.

10212. 'Throughout your generations' means members of the Church with whom the truths and forms of the good of faith are present. This is clear from the meaning of 'generations' as matters of faith and charity, dealt with in the places referred to in 10204. The reason why members of the Church are meant is that real truths and forms of the good of faith and love exist only with them, because with them the Word is present; and the children of Israel (it is their generations who should be understood here) mean the Church, see the places referred to in 9340.
