'Cursed' in the Bible

But the men of Israel were distressed that day. Now Saul had adjured the people, saying, Cursed be the man that eateth food until evening, and until I am avenged on mine enemies. So none of the people tasted food.

Then answered one of the people and said, Thy father strictly adjured the people, saying, Cursed be the man that eateth food this day; and the people are faint.

And the Philistine said to David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.

And now, I pray thee, let my lord the king hear the words of his servant. If Jehovah have moved thee against me, let him accept an oblation; but if the sons of men, cursed be they before Jehovah; for they have driven me out this day from adhering to the inheritance of Jehovah, saying, Go, serve other gods.
