To “generate” something is to create it, and that idea underpins the meaning of a “generation” of people -- it is a group that was created together, at roughly the same time, from the same parents or group of parents. On a spiritual level, we can be “generators” by using what we know from the Lord to create ideas of how to be good, and also to create good actions based on those ideas -- what the Writings call things of faith and things of charity. In general, then, a “generation” in the Bible represents the spiritual ideas and activities created by a church -- with a “church” being anything from an individual believer to a group lasting thousands of years. “Generation” can also pick up specific meanings from context. For instance, when the Bible says the people of Israel were captive in Egypt for four generations, it means a state of temptation based on the meaning of “four.” When paired with “eternity,” meanwhile, “generations” represents ideas and actions surrounding love of serving others, with “eternity” representing things springing from love of the Lord. Finally, “generations and generations” is used in the Bible to represent forever.

7828. 'The first shall it be for you in the months of the year' means the starting point of all states following for evermore. This is clear from the meaning of 'being the first', when used in reference to months of the year and in the internal sense to states of life, as the starting point; from the meaning of 'the months' as states, dealt with immediately above in 7827; and from the meaning of 'the year' as the period of life from start to finish, dealt with in 2906. Here, since it is speaking about members of the spiritual Church in the next life, whose period of life has a starting point but no finish, 'the year' means the period of life from the start and continuing for evermore (as 'year' can also mean, see end of 2906). The reason why this month became 'the head of months' and the first of all is that it means the starting point in the deliverance of those belonging to the spiritual Church who till then were in a state of captivity, since they were held back on the lower earth, where they were molested by the evil ones represented by Pharaoh and the Egyptians. The reason why their first state when they were delivered is the chief one of all and why it is the starting point of all following for evermore is that those who were there were delivered by the Lord's Coming into the world. They could not possibly have been saved without the Lord's Coming into the world; and their deliverance took place when the Lord rose again. From this it is evident that that state - when they were delivered - was for them the chief of all states. It was to be the same after that for all who belonged to the spiritual Church. They too could not have been saved unless the Lord had come into the world and glorified His Human, that is, made it Divine. With regard to those who belonged to the spiritual Church before the Lord's Coming, that they were held back on the lower earth, and that the Lord delivered and saved them, see 6854, 6914; and in general, that members of the spiritual Church were saved by the Lord's Coming, 2661, 1716, 6372, 7035, 7091 (end). So it is that the words under consideration here mean in the highest sense that the glorification and resurrection of the Lord, of His Human, are the source of all salvation.
