Numbers 6:14

and he shall offer his offering to Yahweh: one male lamb a year old without defect for a burnt offering, one ewe lamb a year old without defect for a sin offering, one ram without defect for peace offerings,

And he shall offer his offering unto the LORD, one he lamb of the first year without blemish for a burnt offering, and one ewe lamb of the first year without blemish for a sin offering, and one ram without blemish for peace offerings,
