Barley used in offerings
Source: Nav
Numbers 5:15
then he is to bring his wife to the priest. He must also bring for her an offering of a tenth of an ephah of barley flour. He is not to pour oil over it or put frankincense on it, because it is a grain offering for jealousy, an offering of memorial as a reminder of iniquity.
Ezekiel 45:15
And one sheep shall be given from each flock of two hundred from the well-watered pastures of Israel. These are for the grain offerings, burnt offerings, and peace offerings, to make atonement for the people, declares the Lord GOD.
