Jonathan uses this hypothetical question to state that the people should have been allowed to eat. This can be a statement. AT: "Our victory would have been better if the people had eaten freely today of the plunder that they took from their enemies." (See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-hypo]])
# plunder
This word refers to the things the people had taken from the battle with their enemy.
Because the troops were not able to eat during the battle, as the day progressed, they became weaker. Because of this, they were not able to kill as many of the Philistines.
