636. And they shall prophesy a thousand two hundred and sixty days, signifies that they shall teach, and what shall be taught, even to the end of the old church and the beginning of the new. This is evident from the signification of "to prophesy," as being to teach (See above, n. 624); here both to teach and to be taught, for this is said of "the two witnesses," which signify the good of love and charity and the truth of doctrine and faith, for these with man are what teach and what also are taught; for those who are in the goods of love and in the truths of doctrine teach, and the goods of love and the truths of doctrine are what are taught by them. It is evident also from the signification of "a thousand two hundred and sixty days," as being even to the end of the old church and the beginning of the new, for "a thousand two hundred and sixty days" have a similar signification as "three and a half," since a thousand two hundred and sixty days make three years and a half, computing three hundred and sixty days to the year, and "three and a half" signifies the end of a former state and the beginning of a new one, here the end of the former church and the beginning of the new one, for this refers here to the last time of the church. Because this is the signification of this number, it is said in the ninth verse of this chapter:

They shall see their bodies three days and a half, and shall not suffer them to be placed in sepulchers;

and afterwards in the eleventh verse:

And after three days and a half the spirit of life from God entered into them.

In these passages "three days and a half" signify the end of the old church, when no good of love or truth of doctrine whatever will be received; and also the beginning of a new church when they will be received. The end of the former church is signified by "the beast that cometh up out of the abyss shall kill these witnesses," and the beginning of the new church is signified by "the spirit of life from God entered into them." The number "a thousand two hundred and sixty" has a similar signification as "three and a half," because in the Word "ages," "years," "months," "weeks," "days," and "hours," have a like signification, for these mean merely times, and times in general and in particular, or times greater or less, equally signify states, for a greater or less time designated by numbers does not change the signification of the thing (as shown above, n.571, 633). The same number of days has a like signification in the next chapter of Revelation:

And the woman fled into the wilderness, where she hath a place prepared by God, that there they may nourish her a thousand two hundred and sixty days (Revelation 12:6).

The "woman" here means the church; the "wilderness," where she should be nourished, signifies where there is no reception of good and truth; and "after the passing of those days" signifies a new state of the church.

476. And have made their robes white in the blood of the Lamb, signifies the implantation of Divine truth from the Lord. This is evident from the signification of "making robes white," as meaning to put off falsities and to put on truths, for "white" and "to be made white," are predicated of truths, and these are signified by "robes." (That "white" and "to be made white," are predicated of truths, see above, n. 196; and that "robes" signify truths in general see above, n. 395.) It is said "made their robes white," because the garments of those who are in falsities appear in the spiritual world dusky and also spotted, and the garments of those who are in temptations appear filthy; but as soon as they emerge from temptations, as they have then been imbued with Divine truths, white and shining garments without spots appear upon them, as was mentioned just above. This is why "they have made their robes white" signifies that they have put off falsities and put on truths. The above is evident also from the signification of "the blood of the Lamb" as being Divine truth proceeding from the Lord (of which above, n. 329 e New Jerusalem 293, 294, and in the extracts there from the Arcana Coelestia.) This can be seen from this also, that the garments of angels appear glistening from what is white and bright, not from faith in and thought about the blood of the Lord on the cross, but from Divine truth with them from the Lord; for, as was said above, their garments are all in accord with the truths with them; nor is any angel permitted to think of the Lord's passion, but only of His glorification, and of the reception by Him of the Divine.); and because in temptations falsities are shaken off, and truths are implanted, so in general, "they have made their robes white in the blood of the Lamb" signifies the implantation of Divine truth from the Lord. In the sense of the letter of the Word, "the blood of the Lamb" means the passion of the cross, but in the internal or spiritual sense it means Divine truth proceeding from the Lord; for it is by this that man is purified from falsities and evils, that is, his garments are made white. The passion of the cross was the Lord's last temptation, by which He fully subjugated the hells, and glorified His Human; and when this was accomplished and completed, the Lord sent the Comforter, the Spirit of Truth, by which is meant Divine truth proceeding from His glorified Human, as the Lord teaches in John (John 7:39) and elsewhere. It is by means of Divine truth, when it is received, that man is reformed and regenerated by the Lord and saved, and not by the shedding of blood on the cross. (On this more may be seen in The Doctrine of the New Jerusalem 293-294.)
