(24) An altar of earth thou shalt make unto me.--The earliest altars were, naturally, either of earth, or of unhewn stones, gathered into a heap, since these could be constructed with little labour, and without tools. But, as civilisation advanced, more elaborate structures took the place of the primitive ones. It became usual to erect altars of hewn stone, adorned with carvings more or less rich, among which might often be introduced human and animal forms. We must understand the command here given, and that of Exodus 20:25, as intended to forbid structures of this latter kind, which, if allowed, might have led on to idolatry.

Thy burnt offerings and thy peace offerings.--Sacrifice began soon after Paradise was quitted (Genesis 4:3-4), and shortly became a universal practice. Noah offered sacrifice on leaving the ark (Genesis 8:20); and in the family of Abraham the rite was an established one (Genesis 12:7; Genesis 15:9; Genesis 22:7; Genesis 26:25; Genesis 31:54, &c.). Egyptians, Assyrians, Babylonians, Persians, Ph?nicians, Greeks, Romans, Scythians, Celts, Germans, all equally regarded sacrifice as a main element of their religion; and if the Hebrews had not offered actual sacrifices during their oppression in Egypt, they had, at any rate, maintained the wish to offer them, and it was (primarily) for the purpose of sacrificing that they had quitted Egypt. The legislation assumes that they are acquainted with the difference between "burnt offerings and "peace offerings," and desirous of offering both kinds.

Verse 24. - An altar of earth. Among the nations of antiquity altars were indispensable to Divine worship, which everywhere included sacrifice. They were often provided on the spur of the occasion, and were then "constructed of earth, sods, or stones, collected upon the spot." The patriarchal altars bad probably been of this character, and it was now provided that the same usage should continue: at any rate, elaborate structures of hewn and highly ornamented stone should not be allowed, lest thus idolatry should creep in, the images engraved upon the altars becoming the objects of worship. Thy burnt offerings and thy peace offerings. The mode in which these are introduced implies that sacrifice was already a long-standing practice. The patriarchal sacrifices are well known (Genesis 8:20; Genesis 12:7; Genesis 22:9; Genesis 35:1). Jethro had recently offered sacrifice in the camp of Israel (Exodus 18:12). If the Israelites had not sacrificed to God during the sojourn in Egypt, at any rate they had kept up the idea of sacrifice; and it was for the purpose of offering sacrifices that Moses had demanded permission to go with all his nation into the wilderness. I will come unto thee and I will bless thee. The promise is conditional on the observance of the command. If the altars are rightly constructed, and proper victims offered, then, in all places where he allows the erection of an altar, God will accept the sacrifices offered upon it and bless the worshippers.

20:22-26 Moses having entered into the thick darkness, God there spake in his hearing all that follows from hence to the end of chap. 23, which is mostly an exposition of the ten commandments. The laws in these verses relate to God's worship. The Israelites are assured of God's gracious acceptance of their devotions. Under the gospel, men are encouraged to pray every where, and wherever God's people meet in his name to worship him, he will be in the midst of them; there he will come unto them, and will bless them.An altar of earth thou shall make unto me,.... This was a temporary precept, and only in force until the tabernacle was built, and respects occasional altars, erected while on their travels, and were to be made of turfs of earth, and so easily and quickly thrown up, as their case and circumstances required, and as easily thrown down, as it was proper they should, after they had no more use for them, lest they should be abused to superstitious uses; for afterwards the altar for burnt offerings was made of Shittim wood covered with brass, and that in the temple was wholly a brazen one, Exodus 27:1 this precept seems to suggest the plainness and simplicity in which God would be worshipped, in opposition to the pomp and gaudy show of idolaters intimated in the preceding verse; though Tertullian (t) relates of the Romans in the times of Numa Pomptitus, that they had neither images, nor temples, nor capitols, only altars made of turfs of earth hastily thrown up; and this altar of earth might be, as Ainsworth observes, a figure of the earthly or human nature of Christ, who is the altar, whereof believers in him have a right to eat, Hebrews 13:10.

and shalt sacrifice thereon thy burnt offerings, and thy peace offerings, thy sheep, and thine oxen; which were the creatures offered in the said sacrifices, as also in the sin offerings and trespass offerings, which, though not mentioned, are included:

in all places where I record my name; or, "cause it to be mentioned", or "remembered" (u); where he manifested himself, displayed the glory of his nature and perfection; or, as the Targum of Jonathan expresses it, caused his Shechinah or divine Majesty to dwell, or gave any intimations of his presence, as at the altar now erected to him, and at the sacrifices offered up thereon, and afterwards in the tabernacle, between the cherubim over the mercy seat, and ark of the testimony; which was removed to various places before the temple was built at Jerusalem, where he took up his residence, and his name was called upon, made mention of, and recorded for many generations: but that being destroyed and worship there at an end, men may now worship God in any place, so be it they do it in spirit and in truth; and wherever the name of God is truly called upon, and the glory of his divine perfection, as displayed in the salvation of sinners by Christ, is set forth, and Christ and him crucified is preached; and mention is made of his name as the only one in which salvation is; of his glorious person and offices, of his righteousness, blood, and sacrifice, for justification, remission of sins, and atonement; and his ordinances are administered, which are memorials of his love and grace; there Jehovah grants his presence:

I will come unto thee: not locally or by change of place, nor by his omnipresence merely, so he is everywhere; nor in any visible way, but in a spiritual manner, by the communications of his grace and favour, see John 14:21, and I will bless thee; with his presence, than which nothing is more desirable and delightful; with the supplies of his grace, with peace and pardon, with a justifying righteousness, with a right and title to eternal life, with enlarged views of these blessings and of interest in them.
