No victim was to be offered in sacrifice until it was a week old. The meaning of this law appears to be that the animal should realise a distinct existence in becoming less dependent on its mother, and able to provide for its own wants.

When a bullock - is brought forth - This is a most unfortunate as well as absurd translation. The creature called an ox is a bull castrated; surely then a bullock was never yet brought forth! The original word שור shor signifies a bull, a bullock, or indeed any thing of the neat kind: here, even common sense required that it should be translated calf; and did I not hold myself sacredly bound to print the text of the common version with scrupulous exactness, I should translate the former clause of this verse thus, and so enter it into the text: When a Calf, or a Lamb, or a Kid is brought forth, instead of, When a bullock, a sheep, or a goat is brought forth, the absurdity of which is glaring.

Seven days under the dam - In vindication of the propriety of this precept it may be justly asserted, that the flesh of very young animals is comparatively innutritive, and that animal food is not sufficiently nourishing and wholesome till the animal has arrived at a certain growth, or acquired the perfection of its nature. There is something brutish in eating the young of beast or fowl before the hair and hoofs are perfect in the one, and the feathers and claws in the other. Before this period their flesh is not good for food. See the note on Leviticus 9:1.

When a bullock, or a sheep, or a goat, is brought forth,.... Those three are only mentioned, because they were only made use of in sacrifice, to which this law refers:

then it shall be seven days under the dam; whether a calf, or a lamb, or a kid of the goats; it was not to be taken from its dam and killed, either for food or sacrifice, before it was seven days old: Fagius says, the Hebrews give two reasons why a creature might not be offered before the eighth day; one is, that a sabbath might pass over it, nothing being perfect and consistent without it, that giving, as they say (d) perfection and consistence to all the things of the world; and the other, as the heavens and the earth being perfected in seven days, a creature which lives so long seems to be, as it were, perfect; but he observes, if we inquire after the mystical sense of it, a better reason is to be given, namely, that Christ, the type of all the sacrifices, was not to be offered, or suffer death in his infancy, which Herod contrived, but at man's estate; and to show that no man is fit to be a propitiatory sacrifice, through weakness and inability, being unable to stand before the justice of God, only Christ, in whom is perfection of strength:

and from the eighth day and thenceforth it shall be accepted for an offering made by fire unto the Lord; become an acceptable burnt offering to God; so Pliny (e) says, that the young of sheep are fit for sacrifice on the eighth day, and of an ox on the thirtieth day; see Exodus 22:30.

(d) Tzerer Hammor, fol. 104. 2.((e) Nat. Hist. l. 8. c. 51.

A young ox, sheep, or goat was to be seven days under its mother, and could only be sacrificed from the eighth day onwards, according to the rule laid down in Exodus 22:29 with regard to the first-born. The reason for this was, that the young animal had not attained to a mature and self-sustained life during the first week of its existence.

(Note: For this reason the following rule was also laid down by the Romans: Suis faetus sacrificio die quinto purus est, pecoris die octavo, bovis tricesimo (Plin. h. n. 8, 51).)

This maturity was not reached till after the lapse of a week, that period of time sanctified by the creation. There is no rule laid down in the law respecting the age up to which an animal was admissible in sacrifice. Bullocks, i.e., steers or young oxen of more than a year old, are frequently mentioned and prescribed for the festal sacrifices (for the young ox of less than a year old is called עגל; Leviticus 9:3), viz., as burnt-offerings in Leviticus 23:18; Numbers 7:15, Numbers 7:21, Numbers 7:27, Numbers 7:33, Numbers 7:39.; Numbers 8:8; Numbers 15:24; Numbers 28:11, Numbers 28:19, Numbers 28:27; Numbers 29:2, Numbers 29:8, and as sin-offerings in Leviticus 4:3, Leviticus 4:14; Leviticus 16:3; - sheep (lambs) of one year old are also prescribed as burnt-offerings in Leviticus 9:3; Leviticus 12:6; Leviticus 23:12; Exodus 29:38; Numbers 6:14; Numbers 7:17, Numbers 7:21, Numbers 7:27, Numbers 7:33, Numbers 7:39., Numbers 28:3, Numbers 28:9, Numbers 28:19, Numbers 28:27; Numbers 29:2, Numbers 29:8, Numbers 29:13, Numbers 29:17., as peace-offerings in Numbers 7:17, Numbers 7:23; Numbers 29:35., and as trespass-offerings in Numbers 6:12; also a yearling ewe as a sin-offering in Leviticus 14:10 and Numbers 6:14, and a yearling goat in Numbers 15:27. They generally brought older oxen or bullocks for peace-offerings (Numbers 7:17; Numbers 23:29.), and sometimes as burnt-offerings. In Judges 6:25 an ox of seven years old is said to have been brought as a burnt-offering; and there can be no doubt that the goats and rams presented as sin-offerings and trespass-offerings were more than a year old.

When a bullock, or a sheep, or a goat, is brought forth, then it shall be seven days under the dam; and from the eighth day and thenceforth it shall be accepted for an offering made by fire unto the LORD.

27, 28. it shall be seven days under the dam-Animals were not considered perfect nor good for food till the eighth day. As sacrifices are called the bread or food of God (Le 22:25), to offer them immediately after birth, when they were unfit to be eaten, would have indicated a contempt of religion; and besides, this prohibition, as well as that contained in Le 22:28, inculcated a lesson of humanity or tenderness to the dam, as well as secured the sacrifices from all appearance of unfeeling cruelty.

22:1-33 Laws concerning the priests and sacrifices. - In this chapter we have divers laws concerning the priests and sacrifices, all for preserving the honour of the sanctuary. Let us recollect with gratitude that our great High Priest cannot be hindered by any thing from the discharge of his office. Let us also remember, that the Lord requires us to reverence his name, his truths, his ordinances, and commandments. Let us beware of hypocrisy, and examine ourselves concerning our sinful defilements, seeking to be purified from them in the blood of Christ, and by his sanctifying Spirit. Whoever attempts to expiate his own sin, or draws near in the pride of self-righteousness, puts as great an affront on Christ, as he who comes to the Lord's table from the gratification of sinful lusts. Nor can the minister who loves the souls of the people, suffer them to continue in this dangerous delusion. He must call upon them, not only to repent of their sins, and forsake them; but to put their whole trust in the atonement of Christ, by faith in his name, for pardon and acceptance with God; thus only will the Lord make them holy, as his own people.
