'Faint' in the Bible

Then one of the people answered, and said, "Your father directly commanded the people with an oath, saying, 'Cursed is the man who eats food this day.'" The people were faint.

They struck of the Philistines that day from Michmash to Aijalon. The people were very faint;

But David pursued, he and four hundred men; for two hundred stayed behind, who were so faint that they couldn't go over the brook Besor.

David came to the two hundred men, who were so faint that they could not follow David, whom also they had made to stay at the brook Besor; and they went forth to meet David, and to meet the people who were with him. When David came near to the people, he greeted them.
