6418. 'The son of a fertile one beside a spring' means the fruitfulness of truth from the Word. This is clear from the meaning of 'the son' as truth, dealt with in 489, 491, 533, 2623, 2803, 2813, 3773, 3704; from the meaning of 'a fertile one' as the fruitfulness of truth, for fertility, like bearing and birth, applies in the spiritual sense to truth and good, 1145, 1255, 3860, 3868, 4070, 4668, 5598; and from the meaning of 'a spring' as the Word, dealt with in 2702, 3424, 4861. From this it is evident that 'the son of a fertile one beside a spring' means the fruitfulness of truth from the Word. Those who belong to the Lord's spiritual Church, the Church represented here by 'Joseph', come to know what good is from truth received from the Word, and so are introduced into good by means of truth. Then follows the fruitfulness meant by 'a fertile one'.

4668. 'These are the generations of Jacob' means the things that follow. This is clear from the meaning of 'generations' as derivatives of the things which constitute the Church - truth derived from good, or faith from love - for no other generations are meant in the internal sense of the Word. These are also the subject in what follows, and this is why it is said that 'the generations of Jacob' means the things which follow. That things like these are meant by 'generations' is also evident from the fact that in what follows no subsequent generations are recorded. Instead Joseph, his dreams, his brothers' designs against him are described, and lastly the carrying away of him into Egypt. As regards 'generations' meaning derivatives of the kinds of things mentioned above, see 1145, 1255, 1330, 3263, 3279, 3860, 3868, 4070.
