'Cursed' in the Bible

and the men of Israel were worn out that day, for Saul had placed the troops under an oath: “The man who eats food before evening, before I have taken vengeance on my enemies is cursed.” So none of the troops tasted any food.

Then, one of the troops said, “Your father made the troops solemnly swear, ‘The man who eats food today is cursed,’ and the troops are exhausted.”

He said to David, “Am I a dog that you come against me with sticks?” Then he cursed David by his gods.

Now, may my lord the king please hear the words of his servant: If it is the Lord who has incited you against me, then may He accept an offering. But if it is people, may they be cursed in the presence of the Lord, for today they have driven me away from sharing in the inheritance of the Lord saying, ‘Go and worship other gods.’
