'Cursed' in the Bible

Now the men of Israel were hard pressed that day, for Saul had made the army agree to this oath: "Cursed be the man who eats food before evening! I will get my vengeance on my enemies!" So no one in the army ate anything.

Then someone from the army informed him, "Your father put the army under a strict oath saying, 'Cursed be the man who eats food today!' That is why the army is tired."

The Philistine said to David, "Am I a dog, that you are coming after me with sticks?" Then the Philistine cursed David by his gods.

So let my lord the king now listen to the words of his servant. If the Lord has incited you against me, may he take delight in an offering. But if men have instigated this, may they be cursed before the Lord! For they have driven me away this day from being united with the Lord's inheritance, saying, 'Go on, serve other gods!'
