An undeserved curse will not come to pass, just as a fluttering bird will not stay in one place. A classic example is the story of Balaam, who had to say, “How can I curse those whom God has not cursed? How can I denounce those whom the Lord has not denounced?” (Numbers 23:8).
This proverb rejects a superstitious view of curses, whereby they are viewed as magical things with power in themselves.
2 Comme l'oiseau s'échappe, comme l'hirondelle s'envole,Ainsi la malédiction sans cause n'a point d'effet.
