300# “用七印封严了”表示完全隐藏，即天上和地上所有人的生命状态。这从“用印封严”和“七”的含义清楚可知：“用印封严”是指被隐藏，因为包含在一本书里的东西用印封严了，就没有人知道，直到它被打开并阅读；“七”是指所有人和所有事物，因而是指完全和完整之物(参看AE 257节)，从而也指全部，因为全部意味着完全和完整。
300. Sealed with seven seals. That this signifies altogether hidden, namely, the state of the life of all in heaven and on the earth, is evident from the signification of being sealed with seals, as denoting to be hid, for what is contained in a book sealed with seals, no one knows before it is opened and read; and from the signification of seven, as denoting all persons and all things, also what is full and whole (concerning which see above, n. 257); thus also altogether, because this means fully and wholly.
300. Sealed up with seven seals, signifies altogether hidden, namely, the state of life of all in heaven and on the earth. This is evident from the signification of "sealed with seals," as being to be hidden, for what is contained in a book sealed up with seals no one knows until it is opened and read; also from the signification of "seven," as being all persons and all things, also what is full and entire (See above, n. 257); thus also altogether, because this means fully and wholly.
300. "Obsignatum sigillis septem." - Quod significet prorsus reconditum, nempe statum vitae omnium in caelo et in terra, constat ex significatione "obsignari sigillis", quod sit recondi; nam quid in libro obsignato sigillis continetur, nemo scit priusquam aperitur et legitur: et ex significatione "septem", quod sint omnes et omnia, ac plenum et totum (de qua supra, n. 257), ita quoque prorsus, quia hoc est plene et in totum.
