Bramble
In Judges 9:14, Isaiah 34:13, and Luke 6:44, this signifies evils that oppose the good of the external and internal man. (Apocalypse Explained 295[10]) The bramble or bush in Exodus 3:2 signifies scientific truth, because all small shrubs signify worldly knowledge, but the greater shrubs themselves signify perception and along with knowledge.
