Mattityahu (Mat) 18:10-14

See that you never despise one of these little ones, for I tell you that their angels in heaven are continually seeing the face of my Father in heaven. “What’s your opinion? What will somebody do who has a hundred sheep, and one of them wanders away? Won’t he leave the ninety-nine on the hillsides and go off to find the stray? And if he happens to find it? Yes! I tell you he is happier over it than over the ninety-nine that never strayed! Thus your Father in heaven does not want even one of these little ones to be lost.
