Wish no ill upon your enemies lest the Almighty God be displeased and rain your ill wishes down on your own head.
Matt 5:43-46
43 “You have heard the law that says, ‘Love your neighbor’[q] and hate your enemy.
44 But I say, love your enemies! Pray for those who persecute you!
45 In that way, you will be acting as true children of your Father in heaven.
For he gives his sunlight to both the evil and the good,
and he sends rain on the just and the unjust alike.
