'Cursed' in the Bible

When he has had her drink the water, if she was defiled and had acted unfaithfully toward her husband, then the contaminated water that brings a curse will enter her and infect her, causing her abdomen to swell and her thigh to waste away. Then she is to be a cursed woman among her people.

Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land: for I wot that he whom thou blessest is blessed, and he whom thou cursest is cursed.

How shall I curse, whom God hath not cursed? or how shall I defy, whom the LORD hath not defied?

Then Balak said to Balaam, What have you done to me? I sent for you so that my haters might be cursed, and see, you have given them a blessing.

He couched, he lay down as a lion, and as a great lion: who shall stir him up? Blessed is he that blesseth thee, and cursed is he that curseth thee.

Then Balak was full of wrath against Balaam, and angrily waving his hands he said to Balaam, I sent for you so that those who are against me might be cursed, but now, see, three times you have given them a blessing.
