'Curses' in the Bible

And the priest shall write these curses in a book, and he shall blot them out with the bitter water:

And in the words which the Lord had given him he said, From Aram Balak has sent for me, the king of Moab from the mountains of the East: come, put curses on Jacob for me and be angry with Israel.

How may I put curses on him who is not cursed by God? how may I be angry with him with whom the Lord is not angry?

And Balak said to him, Come with me now into another place from which you will not be able to see them all, but only the outskirts of them; and you will send curses on them from there.

“He couches, he lies down as a lion,And as a lion, who dares rouse him?Blessed is everyone who blesses you,And cursed is everyone who curses you.”
