Please come now therefore curse me this people; for they are too mighty for me: perhaps I shall prevail, that we may strike them, and that I may drive them out of the land; for I know that he whom you bless is blessed, and he whom you curse is cursed."

Behold, I have received a command to bless. He has blessed, and I can't reverse it.

He couched, he lay down as a lion, as a lioness; who shall rouse him up? Everyone who blesses you is blessed. Everyone who curses you is cursed."
