Philtrum

The philtrum is the vertical midline groove in the upper lip that runs from the top of the lip to the nose. According to the Talmud, (Niddah 30b), and other sources, God sends an angel to each womb just before a baby is born, when the angel touches it between the upper lip and the nose and whispers, “Shh…don’t tell what you know.”
