Not all the animals offered under the Law of Moses were males,
“If he brings a lamb as his sin offering, he shall bring a female without blemish…” (Lev 4:32–35).
One thing is for sure, during the roughly 1500 years that the Law of Moses was in effect, many animals lost their lives because of man’s sins.
Yet, now only one sacrifice has taken care of everyone’s sins, and that one sacrifice was so sufficient that it never needs to be offered again.
Jesus of Nazareth, by His one sacrifice, secured the redemption of anyone who wishes to go to the Father.
