"TO BE TOUCHED BY AN ANGEL JUST BEFORE BIRTH"
According to the TaLMUD BaVLeY, NIDaH (30b)...... a certain angel sits besides each and every fetus in their mother's womb.....and teaches them all the wisdom they will ever need to know. But when the child passes into the world, the same angel slaps the child just above the lips, creating vertical groove to be called PHILTRUM, and the child forget everything he learnt.
