John Gill Commentary Exodus 25:6

"oil for the light, spices for the anointing oil, and for the sweet incense," — Exodus 25:6 (ASV)

Oil for the light
For the light of the lamps in the candlestick: this was oil olive, as the Targum of Jonathan, and so Jarchi, see (Exodus 27:20) ,

spices for anointing oil ;
for the anointing of Aaron and his sons, and the tabernacle and its vessels, such as pure myrrh, sweet cinnamon, sweet calamus, and cassia:

and for sweet incense ;
from where they had this oil and these spices, it is not easy to say, unless they brought them out of Egypt with them; which is likely, since the deserts of Arabia could not furnish them with them.
