15:19-23 Here is a direction what to do with the firstlings. We are not now limited as the Israelites were; we make no difference between a first calf, or lamb, and the rest. Let us then look to the gospel meaning of this law, devoting ourselves and the first of our time and strength to God; and using all our comforts and enjoyments to his praise, and under the direction of his law, as we have them all by his gift.And if there be any blemish therein,.... In the firstling, as if it be "lame or blind", or have

any ill blemish: thou shall not sacrifice it unto the Lord thy God; blemishes in any beast made it unfit for sacrifices which were required; and so all peace offerings, vows, and freewill offerings, were to be free from any, Leviticus 22:19, such were not fit for an holy sacrifice or an holy feast.
