9558. 'On one branch' means the power of truth derived from good. This is clear from the meaning of 'branch' as truth derived from good, and consequently power, dealt with above in 9555.

3772. 'And water the flock' means that the doctrine was drawn from it. This is clear from the meaning of 'watering', or giving a drink, as giving instruction, dealt with in 3069, 3768, and from the meaning of 'the flock' as people who are governed by the goods and truths of faith, dealt with in 343, 3767. Thus 'watering it' means giving instruction from the Word, and therefore from doctrine.
