5. Mose 15:19

Application of the first-born of Cattle. - From the laws respecting the poor and slaves, to which the instructions concerning the tithes (Deu 14:22-29) had given occasion, Moses returns to appropriation of the first-born of the herd and flock to sacrificial meals, which he had already touched upon in Deu 12:6, Deu 12:17, and Deu 14:23, and concludes by an explanation upon this point. The command, which the Lord had given when first they came out of Egypt (Exo 13:2, Exo 13:12), that all the first-born of the herd and flock should be sanctified to Him, is repeated here by Moses, with the express injunction that they were not to work with the first-born of cattle (by yoking them to the plough or waggon), and not to shear the first-born of sheep; that is to say, they were not to use the first-born animals which were sanctified to the Lord for their own earthly purposes, but to offer them year by year as sacrifices to the Lord, and consume them in sacrificial meals. To this he adds (Deu 15:21, Deu 15:22) that further provision, that first-born animals, which were blind or lame, or had any other bad fault, were not to be offered in sacrifice to the Lord, but, like ordinary animals used for food, could be eaten in all the towns of the land. Although the first part of this law was involved in the general laws as to the kind of animal that could be offered in sacrifice (Lev 22:19.), it was by no means unimportant to point out distinctly their applicability to the first-born, and add some instructions with regard to the way in which they were to be applied. (On Deu 15:22 and Deu 15:23, see Deu 12:15 and Deu 12:16.)

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 die…

15:19 The firstborn males of livestock represented the firstborn sons of Israel who had been spared from death in the tenth plague (Exod 12:12, 29; 13:2, 12; 22:29).
