Moses
Leviticus 1:10BSB·traditional attribution

If, however, one’s offering is a burnt offering from the flock—from the sheep or goats—he is to present an unblemished male.

Matthew Henry Presbyterian @wholebiblehenry

Here we have the laws concerning the burnt-offerings, which were of the flock or of the fowls. Those of the middle rank, that could not well afford to offer a bullock, would bring a sheep or a goat; and those that were not able to do that should be accepted of God if they brought a turtle-dove or a pigeon.

John Gill Reformed Baptist @doctorgill

And if his offering be of the flocks,.... As it might be: namely, of the sheep, or of the goats for a burnt sacrifice; which were both typical of Christ; see Gill on Lev 1:2. he shall bring it a male without blemish; See Gill on Lev 1:3.

if his offering be of the flocks--Those who could not afford the expense of a bullock might offer a ram or a he-goat, and the same ceremonies were to be observed in the act of offering.
