Apocalypse Revealed # 702
702. Three unclean spirits like frogs. This symbolically means that there arose nothing but reasonings and lusts to falsify truths.
Spirits here have the same symbolism as demons, since we are shortly told that they were spirits of demons, and demons symbolize lusts to falsify truths (no. 458). The number three symbolizes all (nos. 400, 505), here nothing but. Frogs symbolize reasonings prompted by lusts, because they croak and are lascivious.
It is apparent from this that three unclean spirits like frogs symbolize nothing but reasonings and lusts to falsify truths.
Frogs here have the same symbolic meaning as the frogs in Egypt, because the destruction of the church among the Egyptians is likewise described by the miracles done, regarding which we are thus told in Exodus:
Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land... (Exodus 8:5-14, cf. Psalms 78:45; 105:30)
And later the frogs were removed, remaining only in the river (Exodus 8:11-13).
Frogs were produced from the waters of Egypt and remained in the river because the waters in Egypt, and especially those in the river there, symbolized doctrinal falsities on which the people based their reasoning.
Exodus 8:5-14
5
Yahweh said to Moses, "Tell Aaron, 'Stretch forth your hand with your rod over the rivers, over the streams, and over the pools, and cause frogs to come up on the land of Egypt.'"
6
Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt.
7
The magicians did the same thing with their enchantments, and brought up frogs on the land of Egypt.
8
Then Pharaoh called for Moses and Aaron, and said, "Entreat Yahweh, that he take away the frogs from me, and from my people; and I will let the people go, that they may sacrifice to Yahweh."
9
Moses said to Pharaoh, "I give you the honor of setting the time that I should pray for you, and for your servants, and for your people, that the frogs be destroyed from you and your houses, and remain in the river only."
10
He said, "Tomorrow." He said, "Be it according to your word, that you may know that there is none like Yahweh our God.
11
The frogs shall depart from you, and from your houses, and from your servants, and from your people. They shall remain in the river only."
12
Moses and Aaron went out from Pharaoh, and Moses cried to Yahweh concerning the frogs which he had brought on Pharaoh.
13
Yahweh did according to the word of Moses, and the frogs died out of the houses, out of the courts, and out of the fields.
14
They gathered them together in heaps, and the land stank.
