'Yearling lamb' in the Bible

And when the days of her cleansing are fulfilled, for a son or for a daughter, she shall bring a yearling lamb for a burnt-offering, and a young pigeon or a turtle-dove for a sin-offering, to the entrance of the tent of meeting, unto the priest.

On the day you wave the sheaf you must also offer a flawless yearling lamb for a burnt offering to the Lord,
