This chapter opens with an expression remarkably characteristic of the entire Mosaic economy. "And He said unto Moses, 'Come up unto the Lord, thou, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel; and worship ye _afar off ... they shall not come nigh_, neither shall the people _go up_ with him." We may search from end to end of the legal ritual, and not find those two precious words, "_draw nigh_." Ah, no; such words could never be heard from the top of Sinai, nor from amid the shadows of the law. They could only be uttered at heaven's side of the empty tomb of Jesus, where the blood of the cross has opened a perfectly cloudless prospect to the vision of faith. The words, "afar off," are as characteristic of the law as "draw nigh" are of the gospel. Under the law, the work was never done which could entitle a sinner to draw nigh. Man had not fulfilled his promised obedience; and the "blood of calves and goats" could not atone for the failure, or give his guilty conscience peace. Hence, therefore, he had to stand "afar off." Man's vows were broken and his sin unpurged; how, then, could he draw nigh? The blood of ten thousand bullocks could not wipe away one stain from the conscience, or give the peaceful sense of nearness as being reconciled to God. However, the "first covenant" is here dedicated with blood. An altar is erected at the foot of the hill, with "twelve pillars, according to the twelve tribes of Israel." "And he sent young men of the children of Israel, which offered burnt-offerings, and sacrificed peace-offerings of oxen unto the Lord. And Moses took half of the blood, and put it in basins; and half of the blood he sprinkled on the altar.... And Moses took the blood, and sprinkled it on the people, and said, 'Behold the blood of the covenant, which the Lord hath made with you concerning all these words.'" Although, as the apostle teaches us, it was "impossible that the blood of bulls and goats could take away sin," yet did it "sanctify to the purifying of the flesh," and, as "a shadow of good things to come," it availed to maintain the people in relationship with Jehovah.
