257. Sealed with seven seals, signifies that it is altogether hidden from angel and man. That "to be sealed with a seal" signifies to be hidden is evident, hence "to be sealed with seven seals" signifies to be altogether hidden, for "seven" signifies all (n. 10), and therefore altogether; that it was altogether hidden from angel and man, is presently said in these words:
And no one in heaven, nor on earth, neither under the earth, was able to open and read the book, neither to look thereon (Rev. 5:3).
Such is the Word to all to whom the Lamb, that is, the Lord, does not open it. Here, because the exploration of all before the Last Judgment is treated of, it is the states of life of all in general and in particular, which are altogether hidden.
