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.

6956. 'In order that they may believe that Jehovah has appeared to you' means in order that they may possess faith with regard to the Lord's Divine Human. This is clear from the meaning of 'believing' as being in possession of faith, not faith that Jehovah or the Lord has been seen with the eyes, but the kind of faith in the Lord that is meant in the spiritual sense; and from the meaning of 'Jehovah has appeared' as the Lord's appearance within His Divine Human, dealt with in 6945, so that 'they may believe that Jehovah has appeared to you' means in order that they may possess faith with regard to the Lord's Divine Human.
