Arcana Coelestia #8529
8529. 'And Moses said to Aaron' means influx. This is clear from the meaning of 'saying' - when the path is from inward Divine Truth, represented by 'Moses', to outward God's truth, represented by 'Aaron' - as influx. For the path along which Divine influx passes lies through the truth that goes forth directly from the Lord, and on into the truth that goes forth in an indirect way. The fact that in the representative sense 'Moses' and 'Aaron' are those kinds of truth, see 7009, 7010, 7382.
Arcana Coelestia #7382
7382. 'Stretch out your hand with your rod' means the power of inward truth directed through outward truth. This is clear from the meaning of 'hand' as spiritual power, which belongs to inward truth, and from the representation of 'rod' as natural power, which belongs to outward truth, both dealt with in 6947, 6948. For the fact that all power in the spiritual world belongs to truth, see 3091, 3787, 4931, 6344, 6423, 6948. Since 'Moses' represents inward law, which is the same as inward truth, and 'Aaron' represents outward law, which is the same as outward truth, and since inward truth flows into outward truth and gives it power, 7381, Moses' word of command to Aaron 'stretch out your hand with your rod' means the power of inward truth directed through outward truth.
