'Lambs' in the Bible

"And on the eighth day he must take two male lambs without defect and one ewe-lamb {in its first year} without defect and three-tenths [of an ephah] of finely milled flour mixed with oil [as] a grain offering and one log of oil.

And, in addition to the bread, you shall present seven {yearling} male lambs without defects and one {young bull} and two rams--they shall be a burnt offering for Yahweh with their grain offering and their libations, an offering made by fire, an appeasing fragrance for Yahweh.

And you shall {offer} one he-goat as a sin offering and two {yearling} male lambs as a sacrifice of fellowship offerings

And the priest shall wave them with the bread of the firstfruits [as] a wave offering {before} Yahweh; in addition to [the] two male lambs, they shall be holy for Yahweh for the priest.
