John Gill Commentary Leviticus 3:6

"And if his oblation for a sacrifice of peace-offerings unto Jehovah be of the flock; male or female, he shall offer it without blemish." — Leviticus 3:6 (ASV)

And if his offering, for a sacrifice of peace offering unto
Lord, be of the flock
As it might be: and be either male or female; which he pleased:

he shall offer [it] without blemish; (See Gill on Leviticus 3:1).
