'Curse' in the Bible

And Jehovah smelled the sweet savor; and Jehovah said in his heart, I will not again curse the ground any more for man's sake, for that the imagination of man's heart is evil from his youth; neither will I again smite any more everything living, as I have done.

and I will bless them that bless thee, and him that curseth thee will I curse: and in thee shall all the families of the earth be blessed.

My father peradventure will feel me, and I shall seem to him as a deceiver. And I shall bring a curse upon me, and not a blessing.

And his mother said unto him, Upon me be thy curse, my son. Only obey my voice, and go fetch me them.
