A bow signifies falsity of doctrine destroying truth, and spear, the falsity of evil destroying good. (Jeremiah 6:23)

(Odkazy: Apocalypse Explained 357)

9145. 'And a stack of grain is consumed' means harm done to accepted truths and forms of the good of faith. This is clear from the meaning of 'a stack' as accepted truth and good of faith. The reason why 'a stack' has this meaning is that it is grain which has already been gathered in, and 'standing grain' means the truth and good of faith while they are being conceived, which is the subject in the very next paragraph.
