We learn to make the menorah and the incense altar. I liked how the goblets at the end of the menorah are upside down so that one can turn the menorah over and spread blessings to the world.
If a person takes so much care in the making of an object, how they must care for taking loving others.
I like too, reading about the menorah, that one is not to use a lit candle (of the six here or eight for Hanukah) for lighting fires, which is why the seventh/ninth candle is there. Here I believe that oil rather than candles were used here.
It is interesting how the senses are engaged here: sight and smell. This would help engage the whole person in the rituals.
