Numbers 15:4

Then shall he that offereth his offering unto the LORD bring a meat offering of a tenth deal of flour mingled with the fourth part of an hin of oil.

Tenth deal - i:e., an omer, the tenth part of an ephah (Exodus 16:36). fourth part of an hin of oil. This element shows it to have been different from such meat offerings as were made by themselves, and not merely accompaniments of other sacrifices.
