Oil for the light. That the sanctuary to be erected would require to be artificially lighted is assumed. Later, a "candlestick" is ordered (Exodus 25:31-37). The people were to provide the oil which was to be burnt in the "candlestick."
In Exodus 27:20, we are told that the oil was to be "pure oil olive beaten." Spices for anointing oil. Anointing oil would be needed for the sanctification of the Tabernacle, the ark, and all the holy vessels, as also for the consecration of Aaron and his sons to the priesthood.
The spices required are enumerated in Exodus 30:23, Exodus 30:24. They consisted of pure myrrh, sweet cinnamon, sweet calamus, and cassia. And for sweet incense. The spices needed for the incense were, according to our translators, stacte, onycha, galbanum and frankincense (Exodus 30:34).
