Frankincense – one of the Gifts of the Magi. Frankincense is actually a Welcoming Gift. When traveling people would get dirty. There was no paved roads or sidewalks. So someone coming into your home would want (need) to get refreshed. For very long distance travelers this might mean a bath and a new set of clothes. But bare minimum was to wash hands and feet. To add to being welcomed into a home – the water would be perfumed. Frankincense is an expensive perfume to present to a very honored guest. Just… don’t let them ingest frankincense – it will destroy kidneys.
