'Cursed' in the Bible

Come now, in answer to my prayer, and put a curse on this people, for they are greater than I: and then I may be strong enough to overcome them and send them out of the land: for it is clear that good comes to him who has your blessing, but he on whom you put your curse is cursed.

How may I put curses on him who is not cursed by God? how may I be angry with him with whom the Lord is not angry?

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 took his sleep stretched out like a lion, and like a she-lion: by whom will his rest be broken? May a blessing be on everyone who gives you blessing, and a curse on everyone by whom you are cursed.

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.
