'Cursed' in the Bible

The men of Israel were distressed that day; for Saul had adjured the people, saying, "Cursed is the man who eats any food until it is evening, and I am avenged of my enemies." So none of the people tasted food.

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.

The Philistine said to David, "Am I a dog, that you come to me with sticks?" The Philistine cursed David by his gods.

Now therefore, please let my lord the king hear the words of his servant. If it is so that Yahweh has stirred you up against me, let him accept an offering. But if it is the children of men, they are cursed before Yahweh; for they have driven me out this day that I shouldn't cling to Yahweh's inheritance, saying, 'Go, serve other gods!'
