Arcana Coelestia # 3025
3025. 'In whose midst I am dwelling' means incompatible things in the maternal human that surround. This is clear from the meaning of 'living in the midst of them', that is to say, of the Canaanites, as those things that are round about, or that surround - things incompatible with truth, as is clear from what has been stated just above about the meaning of 'the daughters of the Canaanites'. These are the things which the Lord received by heredity from the maternal side and which He subsequently cast away when He made His Human Divine, as becomes clear from what has been stated and shown already on the same subject in 1414, 1444, 1573, 2159, 2574, 2649.
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.
