'Curse' in the Bible

Look! I'm about to grant you a blessing and a curse

or a curse if you don't obey the commands of the LORD your God, by turning from the way that I'm commanding you today and following other gods whom you have not known."

because they didn't come to meet you with food and water along the way as you were coming out of Egypt. Instead, they hired Beor's son Balaam from Pethor in Aram-naharaim to curse you.

However, the LORD your God didn't listen to Balaam. The LORD your God turned Balaam's curse into a blessing, because the LORD your God loves you.

The tribes of Reuben, Gad, Asher, Zebulun, Dan, and Naphtali are to stand on Mount Ebal to pronounce the curse.

"The LORD will send the curse among you, will confuse you, and will rebuke you in everything you undertake until you are destroyed and perish quickly because of your evil deeds, since you will have forsaken him.
