Matthew Poole and continuators on Numbers 15:3

3 And will make an offering by fire unto the LORD, a burnt-offering, or a sacrifice in performing a vow, or in a free-will-offering, or in your solemn feasts, to make a sweet savour unto the LORD, of the herd or of the flock:

(i. e.) A peace-offering, as appears 1. because that word put by it self is oft so taken, as Exod. 18. 12. Levit. 17. 5, 8. and 23. 37. Deut. 12. 2[illegible: 1+ letters]. 2. because the offerings for sins and trespasses had no meat-offerings and drink-offerings attending upon them, excepting onely the case of the Lepers cleansing, Levit. 14. 10. 3. because this is explained by and called peace-offerings, ver. 8. 4. from the words here following, because peace-offerings were commonly offered either in performance of a vow, or freely, or by Gods command in their solemn feasts, all which are here expressed.
