1 Samuel 14:24, 28

Saul did something really foolish that day. He addressed the army: “A curse on the man who eats anything before evening, before I’ve wreaked vengeance on my enemies!” None of them ate a thing all day.

A soldier spoke up, “Your father has put the army under solemn oath, saying, ‘A curse on the man who eats anything before evening!’ No wonder the soldiers are drooping!”
