'Curse' in the Bible
Then the priest will have the woman stand before the Lord, uncover the woman's head, and put the grain offering for remembering in her hands, which is the grain offering of suspicion. The priest will hold in his hand the bitter water that brings a curse.
Then the priest will put the woman under oath and say to the her, "If no other man has had sexual relations with you, and if you have not gone astray and become defiled while under your husband's authority, may you be free from this bitter water that brings a curse.
Then the priest will put the woman under the oath of the curse and will say to the her, "The Lord make you an attested curse among your people, if the Lord makes your thigh fall away and your abdomen swell;
and this water that causes the curse will go into your stomach, and make your abdomen swell and your thigh rot." Then the woman must say, "Amen, amen."
He will make the woman drink the bitter water that brings a curse, and the water that brings a curse will enter her to produce bitterness.
When he has made her drink the water, then, if she has defiled herself and behaved unfaithfully toward her husband, the water that brings a curse will enter her to produce bitterness -- her abdomen will swell, her thigh will fall away, and the woman will become a curse among her people.
So now, please come and curse this nation for me, for they are too powerful for me. Perhaps I will prevail so that we may conquer them and drive them out of the land. For I know that whoever you bless is blessed, and whoever you curse is cursed."
"Look, a nation has come out of Egypt, and it covers the face of the earth. Come now and put a curse on them for me; perhaps I will be able to defeat them and drive them out."
But God said to Balaam, "You must not go with them; you must not curse the people, for they are blessed."
For I will honor you greatly, and whatever you tell me I will do. So come, put a curse on this nation for me.'"
Then Balaam uttered his oracle, saying, "Balak, the king of Moab, brought me from Aram, out of the mountains of the east, saying, 'Come, pronounce a curse on Jacob for me; come, denounce Israel.'
How can I curse one whom God has not cursed, or how can I denounce one whom the Lord has not denounced?
Then Balak said to Balaam, "What have you done to me? I brought you to curse my enemies, but on the contrary you have only blessed them!"
Balak said to him, "Please come with me to another place from which you can observe them. You will see only a part of them, but you will not see all of them. Curse them for me from there."
Balak said to Balaam, "Neither curse them at all nor bless them at all!"
Balak said to Balaam, "Come, please; I will take you to another place. Perhaps it will please God to let you curse them for me from there."
Then Balak became very angry at Balaam, and he struck his hands together. Balak said to Balaam, "I called you to curse my enemies, and look, you have done nothing but bless them these three times!
