6778. 'To water their father's flock' means to the end that those governed by good might receive instruction from there. This is clear from the meaning of 'watering' as giving instruction, dealt with in 3772; from the meaning of 'the flock' as those who learn about and are led to the good of charity, dealt with in 343, 3772, 5913, 6048; and from the representation of Reuel, to whom 'father' refers here, and who was a priest, as the good of that Church, a Church where those people are who are guided by the truth that goes with simple good, people dealt with above in 6773, 6775.

6776. 'And they came and drew water' means that they received instruction in truths from the Word. This is clear from the meaning of 'drawing' as receiving instruction in the truths of faith and becoming enlightened, dealt with in 3058, 3071. The Word as the origin of them is meant by 'the well' from which they drew water - for the meaning of 'the well' as the Word, see above in 6774.
