Arcana Coelestia # 679
679. 'He was to gather them for himself' means truths. This is clear from what has been stated above, for 'gathering' has reference to the things that are in a person's memory, where they have been gathered together. It embodies in addition the point that the former and the latter - goods and truths - need to be gathered together in man before regeneration takes place. Indeed unless goods and truths have been gathered together to serve as means through which the Lord may do His work, a person cannot possibly be regenerated, as has been stated. From this it follows then that 'it was to be food for him and them' means both goods and truths.
Genesis 6:4
4
The Nephilim were in the earth in those days, and also after that, when God's sons came in to men's daughters. They bore children to them. Those were the mighty men who were of old, men of renown.
