Samson
Samson's father Manoah, and his wife had been trying to have a baby for many years when an angel showed up in front of their house. The angel told them that they were to have a son, who was to be a Nazarite. The child was to never cut his hair, drink wine, or touch a dead person. A while later, Samson was born, and he obeyed the Nazarite laws just as the angel said.
