Numbers 28:11-12, 20

‘At the beginnings of your months you shall present a burnt offering to the LORD: two young bulls, one ram, and seven lambs in their first year, without blemish; three-tenths of an ephah of fine flour as a grain offering, mixed with oil, for each bull; two-tenths of an ephah of fine flour as a grain offering, mixed with oil, for the one ram

Their grain offering shall be of fine flour mixed with oil: three-tenths of an ephah you shall offer for a bull, and two-tenths for a ram
