AC 9392, 9398, 9399 - And Moses took half of the blood

I apologize for the length of this post. There is a lot of sprinkling of blood in the Old Testament. As someone who as done an awful lot of laundry, blood sprinkled all over - especially the beautiful garments of the priests - just makes me cringe. However, as with everything in the Word, the Lord has His reasons:

AC 9392:
And Moses took half of the blood, and put it into basins;
and half of the blood he sprinkled on the altar.
And he took the book of the covenant,
and read it in the ears of the people;
they said, All that Jehovah hath spoken we will do and hear.
And Moses took the blood, and sprinkled it on the people,
and said, Behold the blood of the covenant
that Jehovah has made with you upon all these words.
(Exodus 24:6-8)

"And Moses took half of the blood,"
signifies Divine truth that has been made of the life and of worship;
"and put it into basins,"
signifies with man in the things of his memory;
"and half of the blood he sprinkled on the altar,"
signifies Divine truth from the Divine Human of the Lord;
"and he took the book of the covenant,"
signifies the Word in the letter
with which the Word in heaven has been conjoined;
"and read it in the ears of the people,"
signifies for hearkening and obedience;
"and they said,
All things that Jehovah hath spoken we will do and hear,"
signifies the reception of the truth
that proceeds from the Divine Human of the Lord,
and obedience from the heart and soul;
"and Moses took the blood, and sprinkled it on the people,"
signifies adaptation to the reception of man;
"and said, Behold the blood of the covenant,"
signifies thereby the conjunction of the Lord
in respect to the Divine Human with heaven and with earth;
"that Jehovah hath made with you upon all these words,"
signifies that there is conjunction with the Lord
through each and all things of the Word.

AC 9398
Obedience from the heart
is obedience from the will,
thus from the affection of love;
and obedience from the soul
is obedience from the understanding, thus from faith . . ..
Therefore it is said, "we will do and hear."

The reason why "all things that Jehovah hath spoken,"
denotes the truth that proceeds from the Divine Human of the Lord,
is that all truth proceeds therefrom.

AC 9399
For the Divine truth which is from the Lord
is continually flowing in with man, and forms his understanding;
and if you will believe it,
without this continual influx of the truth Divine that proceeds from the Lord
a man can perceive and understand nothing whatever.
For the Divine truth that proceeds from the Lord
is the light which lights up the mind of man,
and makes the internal sight,
which is the understanding;
and as this light continually flows in,
it adapts everyone to receive.
But they who receive are they who are in the good of life;
and they who do not receive are they who are in evil of life.
Nevertheless the latter, like the former,
have the capacity of perceiving and understanding,
and also the capacity of receiving,
insofar as they desist from evils.
These things were signified by the half of the blood
which Moses sprinkled on the people.

[3] That every person in the world who is of sound reason
has the capacity of understanding truth Divine,
and consequently the capacity of receiving it,
insofar as he desists from evils . . .
