5912. 'You and your sons, and the sons of your sons' means spiritual good, and all derivatives from it, and further derivatives from these. This is clear from the representation of Israel, to whom 'you' refers here, as spiritual good, dealt with above in 5906; from the meaning of 'his sons' as derivatives from that good, that is, the truths in the natural which are represented by 'his sons'; and from the meaning of 'the sons of his sons' as derivatives from these, that is to say, further truths so born and derived. For when good occupies the first place and has dominion, it is constantly bringing forth truths. It then multiplies these around itself and also around each truth, making each truth like a star, the middle of which is shining brightly. But that good does not merely multiply the truths around itself; it also brings forth from those truths further truths by means of successive derivations, which are 'the sons of sons' or grandsons, and so on after them. Joseph did not invite his brothers to join him except through their father; for he said that his father was to come with his sons and sons' sons. The reason for this is that the joining of the internal celestial to the truths in the natural has no existence except through the intermediary.

7664. 'For it is a feast of Jehovah for us' means worship of the Lord offered by every single one. This is clear from the meaning of 'a feast' as worship with gladness of mind, dealt with in 7093. The reason why it is worship of the Lord is that 'Jehovah' in the Word is the Lord, 1343, 1736, 2921, 3023, 3035, 5663, 6307, 6905, 6945, 6956. The fact that worship by every single one is meant is evident from what comes immediately before, where it says that they would go with children and old men, with sons and daughters, and with flocks and herds.
