'Locusts' signify falsities in the extremes, which consume the truths and goods of the church in a person. 'The locusts' which John the Baptist ate signify truths of a most common or general nature.

(参照: Apocalypse Revealed 424, 430)

6771. And Pharaoh heard this word, and he sought to kill Moses. That this signifies that false memory-knowledge, noticing this, willed to destroy the truth of the law from the Divine, is evident from the signification of “to hear,” as being to notice (see n. 5017); from the representation of Pharaoh, as being memory-knowledge that is opposed to the truths of the church, thus falsity (see n. 6651, 6679, 6683); from the signification of “to kill,” as being to destroy (n. 6767), thus “to seek to kill” is to will to destroy; and from the representation of Moses, as being the law Divine and truth Divine (n. 6752), thus truth which is of the law Divine. It is said “truth of the law Divine,” not “the law Divine,” because the subject treated of is still the progress of the law Divine in the Lord’s Human. From all this it is evident that by “Pharaoh heard this word and sought to kill Moses” is signified that false memory-knowledge, noticing this, willed to destroy the truth which is of the law Divine.
