The Inner Meaning of the Prophets and Psalms #30
30. Internal Meaning of Isaiah, Chapter 30
1-5 Those who trust in the knowledge [scientia] of the natural man, thus in their own intelligence, lead themselves astray. (2)
6 The learned or the self-taught: (2)
7-10 they are led astray by knowledges [scientiae], and they recede from the Word, (2)
12-14 Thus they have no truth and thus again no good. (2, 16)
15 They should have trust in the Lord. (2)
16-17 Those who trust in themselves and in their own learning have no intelligence whatever. (2)
18-19 The Lord turns Himself to those who trust in Him. (11, 2)
20-21 They will be instructed. (11)
22 They will then reject those things pertaining to self-intelligence. (11, 11)
23-26 They will then have truth in all abundance, and wisdom. (11)
27-28 When those who are in the falsities of evil will perish, (15, 3)
29-30 they will then come into the delights of truth and good, from the Lord. (11, 2)
30-31 There will be a judgment on those who trust in themselves. (15)
32-33 Those who have thereby adulterated the Word, will be cast into hell. (15)
