'Curse' in the Bible

Yahweh smelled the pleasant aroma. Yahweh said in his heart, "I will not again curse the ground any more for man's sake, because the imagination of man's heart is evil from his youth; neither will I ever again strike everything living, as I have done.

I will bless those who bless you, and I will curse him who curses you. All of the families of the earth will be blessed in you."

What if my father touches me? I will seem to him as a deceiver, and I would bring a curse on myself, and not a blessing."

His mother said to him, "Let your curse be on me, my son. Only obey my voice, and go get them for me."
