The Prophetical Books:

1. Internal Meaning of Isaiah, Chapter 1 (1)

1-8 The church has been vastated by evil of life, (3)

9 so that there is little of a residue. (3)

10-15 Therefore their external worship is of no avail. (3)

16-19 Exhortation that they should repent of the evil of life, and thus they will receive good. (3)

20-23They falsify the Word. (3)

24-27 The Lord when He comes will destroy them, and will establish the church with others; (1, 11)

28-31 This when nothing of the church remains with them. (3)

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.
