Sons of the stranger
'Sons of the stranger' signify counterfeit truths, or falsities. 'Our sons' signify the doctrines of truth, and 'our daughters,' the doctrines of good, as in Psalm 144:11-12.

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.
