Exodus 29:40-41

40and with the one lamb there shall be one-tenth of a measure of fine flour mixed with one-fourth of a hin of beaten [olive] oil, and one-fourth of a hin of wine for a drink offering [to be poured out].

41And the other lamb you shall offer at twilight, and do with it as with the grain offering of the morning and with the drink offering, for a sweet and soothing aroma [to appease God], an offering by fire to the Lord.
