In Genesis 14:23, this signifies the lowest and most insignificant falsity. (Arcana Coelestia 1748)

In Joshua 2:18, 21, this signifies the truth of the literal sense of the Word. (Apocalypse Explained 1042[6])

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.
