Numbers 28:21

21 a tenth shall you offer for each of the seven lambs;

Numbers 28:21 In-Context

19 but offer an offering by fire, a burnt offering to the LORD: two young bulls, one ram, and seven male lambs a year old; see that they are without blemish;
20 also their cereal offering of fine flour mixed with oil; three tenths of an ephah shall you offer for a bull, and two tenths for a ram;
21 a tenth shall you offer for each of the seven lambs;
22 also one male goat for a sin offering, to make atonement for you.
23 You shall offer these besides the burnt offering of the morning, which is for a continual burnt offering.
