Exodus 30:24

And of cassia five hundred shekels, after the shekel of the sanctuary, and of oil olive an hin:

The formula calls for cassia in the amount of five hundred shekels by the sanctuary shekel, together with olive oil in the amount of one hin. These two ingredients with their stated measures belong to the Lord's special preparation appointed for use in the tabernacle. That preparation is sacred and is not to be treated as common.
