Contradiction with Proverbs 30:27
This verse portrays the locusts as having no king, which contradicts Joel 1:6 where the nation is described as having the teeth of a strong lion, suggesting organization and leadership.
Proverbs 30:27: The locusts have no king, yet go they forth all of them by bands; [by...: Heb. gathered together]
Contradiction with Revelation 9:7-8
This passage describes locusts with the appearance of horses prepared for battle and having teeth like lions', which is somewhat similar to Joel 1:6, but the context of Revelation suggests a divine and apocalyptic origin, contrasting with the natural disaster context in Joel.
Revelation 9:7-8: And the shapes of the locusts [were] like unto horses prepared unto battle; and on their heads [were] as it were crowns like gold, and their faces [were] as the faces of men.
Contradiction with Amos 7:1
This verse describes locusts as part of God's judgment prior to the growth of later crops, which can contrast with Joel's description of immediate destruction by these creatures as a present invasion.
Amos 7:1: Thus hath the Lord GOD shewed unto me; and, behold, he formed grasshoppers in the beginning of the shooting up of the latter growth; and, lo, [it was] the latter growth after the king's mowings. [grasshoppers: or, green worms]
Contradiction with Exodus 10:14
Describes an unprecedented plague of locusts during Moses' time in Egypt. This might contradict Joel 1:6 as it implies that the most significant locust disaster had already occurred in Egypt, rather than in Joel's prophecy.
Exodus 10:14: And the locusts went up over all the land of Egypt, and rested in all the coasts of Egypt: very grievous [were they]; before them there were no such locusts as they, neither after them shall be such.
