'Curse' in the Bible

They clave to their brethren, their nobles, and entered into a curse, and into an oath, to walk in God's law, which was given by Moses the servant of God, and to observe and do all the commandments of Jehovah our Lord, and his ordinances and his statutes;

because they met not the children of Israel with bread and with water, but hired Balaam against them, to curse them: howbeit our God turned the curse into a blessing.
