Charles Ellicott Commentary Leviticus 3:1

"And if his oblation be a sacrifice of peace-offerings; if he offer of the herd, whether male or female, he shall offer it without blemish before Jehovah." — Leviticus 3:1 (ASV)

A sacrifice of peace offering. —The peace offering, which this chapter discusses, consisted of two kinds, the peace offering from the herd (Leviticus 3:1–5), and the peace offering from the flock (Leviticus 3:6–15). As in the case of the burnt offering (Leviticus 1:3), the ox is mentioned first, because it is most costly and more important.

Whether it is a male. —While in the case of the burnt offering (Leviticus 1:3; Leviticus 1:10), only the male was lawful, there is no distinction of sex here, nor is there any limitation of age. All that was required was that it should be without any organic defect.
