David speaks of leading the Israelites in killing the Philistines and leaving their bodies on the ground for the animals to eat them as if he were to give their bodies to the animals. Alternate translation: "We Israelites will kill the Philistine army, and the birds of the heavens and the wild beasts of the earth will eat them" (See: [[rc://en/ta/man/translate/figs-metaphor]])
The word "earth" refers to the people on earth. Alternate translation: "all the people of the earth may know" (See: [[rc://en/ta/man/translate/figs-metonymy]])
