They must have yielded much blood. It is divided into two parts, corresponding to the two parties to the covenant, like the cloven animals in Abraham's covenant. One half is 'sprinkled' on the altar, or, as the word means, 'swung,'--which suggests a larger quantity and a more vehement action than 'sprinkling' does. That drenching of the altar with gore is either a piece of barbarism or a solemn symbol of the central fact of Christianity no less than of Judaism, and a token that the only footing on which man can be received into fellowship with God is through the offering of a pure life, instead of the sinner, which, accepted by God, covers or expiates sin. There can be no question that the idea of expiation is at the very foundation of the Old Testament ritual. It is fashionable to regard the expiatory element of Christianity as 'Hebrew old clothes,' but the fact is the other way about. It is not that Christianity has not been able to rid itself of a rude and false conception, but that 'Judaism' had its sacrifices appointed by God, in order to prepare the way for the true offering, which takes away sin.
The expiation by blood having been thus made, the hindrances to the nation's entering into covenant are removed. Therefore follows in logical order the next step, their formal (alas! how purely formal it proved to be) taking on themselves its obligations. The freshly written 'book' is produced, and read there, to the silent people, before the bloody altar, beneath the peak of Sinai. Again the chorus of assent from a thousand throats echoes among the rocks. They accept the conditions. They had done so last night; but this is the actual contract on their part, and its place in the whole order of the ceremony is significant. It follows expiation, without which man cannot enter into friendship with God, without the acceptance of which man will not yield himself in obedience. The vows which God approves are those of men whose sins are covered.
The final step was the sprinkling of the people with the blood. The division of the blood into two portions signifies that it had an office in regard to each party to the covenant. If it had been possible to pour it all on the altar, and then all on the people, that would have been done. The separation into two portions was inevitable; but in reality it is the same blood which, sprinkled on the altar, expiates, and on the worshipper, consecrates, cleanses, unites to God, and brings into covenant with Him. Hence Moses accompanies the sprinkling of the people with the explanation, 'This is the blood of the covenant, which the Lord hath made with you, upon all these conditions' (Rev. Ver. margin). It ratifies the compact on both sides. God 'hath made' it, in accepting the sprinkled blood; they have made it, in being sprinkled therewith. But while the rite sets forth the great gospel truth of expiation, the Covenant moves within the region of law. It is made 'on the basis of all these words,' and is voidable by disobedience. It is the _Magna Charta_ of the nation, and its summing up is 'this do, and thou shalt live.' Its promises are mainly of outward guardianship and national blessings. And these are suspended by it, as they were in fact contingent, on the national observance of the national vow. The general idea of a covenant is that of a compact between two parties, each of whom comes under obligations contingent on the other's discharge of his. Theologians have raised the question whether God's covenant is of this kind. Surely it is. His promises to Israel had an 'if,' and the fulfilment of the conditions necessarily secured the accomplishment of the promises. The ritual of the first covenant transcends the strictly retributive compact which it ratified, and shadows a gospel beyond law, even the new covenant which brings better gifts, and does not turn on 'do,' but simply on the sprinkling with the blood of Jesus. The words of Moses were widened to carry a blessing beyond his thoughts, which was disclosed when, in an upper chamber, a dying man said to the twelve representatives of the true Israel, 'This is the new covenant in My blood, drink ye all of it.' The blood which Moses sprinkled gave ritual cleansing, but it remained outside the man. The blood of Jesus gives true purification, and passes into our veins to become our life. The covenant by Moses was 'do and live'; that in Christ is 'believe and live.' Moses brought commandments, and on them his covenant was built; Christ brings gifts, and His covenant is all promises, which are ours on the simple condition of taking them.
