Here is, 1. A repetition of the law concerning the firstlings of their cattle, that, if they were males, they were to be sanctified to the Lord (Deu 15:19), in remembrance of, and in thankfulness for, the sparing of the first-born of Israel, when the first-born of the Egyptians, both of man and beast, were slain by the destroying angel (Exo 13:2, Exo 13:15); on the eighth day it was to be given to God (Exo 22:30), and to be divided between the priest and the altar, Num 18:17, Num 18:18. 2. An addition to that law, for the further explication of it, directing them what to do with the firstlings, (1.) That were females: "Thou shalt do no work with the female firstlings of the cow, nor shear those of the sheep" (Deu 15:19); of them the learned bishop Patrick understands it. Though the female firstlings were not so entirely sanctified to God as the males, nor so early as at eight days old, yet they were not to be converted by the owners to their own use as the other cattle, but must be offered to God as peace-offerings, or used in a religious feast, at the year's end, Deu 15:20. Thou shalt eat it before the Lord thy God, as directed Deu 12:18. (2.) But what must they do with that which was blemished, ill-blemished? Deu 15:21. Were it male or female, it must not be brought near the sanctuary, nor used either for sacrifice or for holy feasting, for it would not be fit to honour God with, nor to typify Christ, who is a Lamb without blemish; yet it must not be reared, but killed and eaten at their own houses as common food (Deu 15:22), only they must be sure not to eat it with the blood, Deu 15:23. The frequent repetition of this caution intimates what need the people had of it, and what stress God laid upon it. What a mercy it is that we are not under this yoke! We are not dieted as they were; we make no difference between a first calf, or lamb, and the rest that follow. Let us therefore realize the gospel meaning of this law, devoting ourselves and the first of our time and strength to God, as a kind of first-fruits of his creatures, 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, Lev 22:19, such were not fit for an holy sacrifice or an holy feast.

All the firstling males of thy herd and of thy flock thou shalt sanctify unto the Lord thy God--[See on Exo 13:2]; see Exo 22:30).

thou shalt do not work with the firstling of thy bullock--that is, the second firstlings (see Deu 12:17-18; Deu 14:23).
