7326. And they shall be blood. That this signifies that they shall falsify truths, is evident from the signification of “blood” as being the falsification of truth (see n. 7317). “Blood” in the genuine sense signifies the holy of love, thus charity and faith, for these are the holy things of love; thus “blood” signifies holy truth proceeding from the Lord (see n. 1001, 4735, 6978). But in the opposite sense “blood” signifies violence done to charity, and also to faith, thus to the holy truth proceeding from the Lord; and as violence is done to truth when it is falsified, by “blood” is signified the falsification of truth, and in a greater degree by “blood” is signified the profanation of truth. This was signified by the eating of blood, which was for this reason so severely forbidden (n. 1003).

1003. From these things it is now evident that “not to eat flesh with the soul thereof, the blood thereof” is not to mingle profane things with holy. Profane things are not mingled with holy by one’s eating blood with flesh, as the Lord clearly teaches in Matthew:

Not that which entereth into the mouth defileth the man; but that which proceedeth out of the mouth, this defileth the man; for the things which proceed out of the mouth come forth out of the heart (Matthew 15:11, 18-20). But in the Jewish Church it was forbidden because, as has been said, by the eating of blood with the flesh there was then in heaven represented profanation. All things done in that church were turned in heaven into corresponding representatives—blood into the holy celestial; flesh, outside of the sacrifices, because it signified cupidities, into what is profane; and the eating of both into the mingling of the holy with the profane. For this reason it was then so severely interdicted. But after the coming of the Lord, when external rites were abolished, and thus representatives ceased, such things were no longer turned in heaven into corresponding representatives. For when man becomes internal and is instructed about internal things, external ones are of no account to him. He then knows what the holy is, namely, charity and the faith therefrom. According to these are his external things then regarded, that is to say, according to the amount of charity and faith in the Lord there is in them. Since the coming of the Lord, therefore, man is not regarded in heaven from external things, but from internal ones. And if anyone is regarded from external things it is because he is in simplicity, and in his simplicity there are innocence and charity, which are in his external things, that is, in his external worship, from the Lord, without the man’s knowledge.

6978. They shall become blood in the dry [land]. That this signifies the falsification of all truth, and the consequent privation of it in the natural, is evident from the signification of “blood,” as being holy truth proceeding from the Lord, and in the opposite sense truth falsified and profaned (see n. 4735, how the case herein is was shown just above); and from the signification of “the dry [land],” as being the natural (of which also just above, n. 6976). That “blood” signifies the falsification of truth and its profanation, is especially evident in Nahum:

Woe to the city of bloods! It is all full of lying and rapine; the prey departeth not. The voice of a whip, and the voice of the sound of a wheel; and a neighing horse, and a jumping chariot; the horseman mounting, and the shining of a sword, and the flash of a spear; and a multitude of pierced, and a heap of carcass and no end of body; they stumble on their body. Because of the multitude of the whoredoms of the well-favored harlot, the mistress of witchcrafts, that selleth nations through her whoredoms, and families through her witchcrafts (Nah. 3:1-4).

That by the “city of bloods” is signified the doctrine of falsity, thus by “blood,” falsified and profaned truth is plain from all the words of its description in the internal sense, and not only in these verses which have been cited, but also in those which follow, the description of it being continued in the whole chapter; for the “city” is doctrine; its being “all full of lying and rapine” denotes being full of falsity, and of evil from falsity; “the voice of a whip and the voice of the sound of a wheel” denotes the defence of falsity by fallacies; “a neighing horse and a jumping chariot” denotes from a perverted intellectual and the like doctrine; “the horseman mounting, the shining of a sword, the flashing of a spear” denotes combat against truth; “the multitude of pierced” denotes innumerable falsities thence, and those who are in falsities; “a heap of carcass, and no end of body” denotes innumerable evils thence, and those who are in evils; “the whoredoms of a harlot” denote the falsifications themselves, and in like manner “witchcrafts.”
