Apocalypse Explained#620
620. And I took the little book out of the angel's hand, and ate it up.- That this signifies exploration, is evident from what precedes, namely, that by the little book is meant the Word, by the angel, the Lord as to the Word, and by devouring or eating it up, the reception, perception, and appropriation of it to oneself, consequently also exploration, in this case as to the quality of the understanding of the Word still remaining in the church. Exploration takes place by means of that which is perceived and according to perception; exploration therefore took place with the prophet John, because a prophet signifies the doctrine of the church, and in a universal sense the Word.
Arcana Coelestia#8055
8055. 'Which He swore to your fathers to give you' means which the Divine promised to those governed by goodness and truth. This is clear from the meaning of 'swearing', when done by Jehovah, as unchangeable confirmation from the Divine, 2842, 3375, so that 'swearing to give' means a promise; and from the meaning of 'fathers' as those governed by goodness and truth, for when the Church is the subject 'fathers' means the ancients, that is, the Ancient Churches, which were governed by goodness and truth, 6050, 6075, 6589, 6876, 6884, 7649.
