Arcana Coelestia # 3174
3174. 'Her brother said, and her mother' means doubt on the part of the natural man. This is clear from the meaning of 'a brother' as the good within the natural man, dealt with in 3160, and from the meaning of 'a mother' as the truth there, dealt with in 3167. Consequently 'brother' and 'mother' mean the natural man since this is composed of good and truth. The fact that doubt is meant is self-evident, that is to say, doubt whether the girl would stay a few days longer or whether she would go with the man there and then.
Foot
The foot, as in Deuteronomy 33:3, signifies an inferior principle. To set the right foot on the sea and the left on the earth, as in Revelation 10:2, signifies that the Lord has the universal church under His intuition and dominion.
