Like a sparrow in flitting, like a swallow in its flying, a curse that is causeless does not alight. (ESV) Proverbs 26:2
Nosh: Several times in my life, I have found this verse comforting and reassuring. Put this one in your back pocket for an appropriate situation. Never be afraid of or disturbed by those who say that they or someone has laid an evil curse or spell on you. God says that unjustified or causeless curses have no effect on the righteous.
