Both "swords" and "bows" are weapons used to attack people. The fact that they are "drawn" and "bent" means they are ready to start attacking. AT: "have prepared their weapons in order to attack" (See: [[rc://en/ta/man/translate/figs-synecdoche]])
This destruction of the needy people is spoken of as if they were clay pots that would break into pieces when thrown down on the ground. AT: "to destroy" (See: [[rc://en/ta/man/translate/figs-metaphor]])
These terms both refer to people who are powerless to defend themselves. AT: "people who are not able to resist them" (See: [[rc://en/ta/man/translate/figs-doublet]])
Swords are examples of weapons and "hearts" represent the people. To "pierce the heart" is an idiom that means "to kill." AT: "Their weapons will be turned against them and they will kill themselves" (See: [[rc://en/ta/man/translate/figs-synecdoche]] and [[rc://en/ta/man/translate/figs-idiom]])
