Hence, the cry of Isaiah, when he beheld the glory of the Lord: “Woe is me! for I am undone, because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for mine eyes have seen the King, the Lord of hosts.” And hence, the coal of fire from off the altar of atonement, and the seraph’s assurance, “Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.”—Isa. vi, 5-7. Thus, every way, under the idea of indwelling defilement, was sin and its source in man’s corrupted nature held up to Israel as loathsome in itself, propagated to the race and infecting all, defiling in its contact, deadly in its indwelling power, and abhorrent to the eyes of God. Four circumstances in the ritual on these defilements are peculiar and characteristic: 1. The first of these exhibits a broad and fundamental contrast between these defilements and those which continued only till the even. The latter, as already intimated, presented the conception of an outward soiling of the living person. But the uncleanness of seven days exhibited the idea, not of surface defilement of the living, but of the loathsomeness and pollution of the dead and decaying carcass, pouring out its own corruption, and infecting all around with its unclean and abhorrent presence,—a pollution which no extrinsic or surface washing can ever cleanse. 2. The defilement was for seven days. God’s work of creation ended in the rest of the seventh day. That day was hence appropriated as a type of the final rest of Christ and his people upon the completed work of redemption. Hence, the argument of Paul: “For he spake of the seventh day on this wise, And God did rest the seventh day from all his works. And in this place again, If they shall enter into my rest. There remaineth therefore a rest for the people of God.”—Heb. iv, 4-9. “A rest:” literally, as in the margin, “a keeping of a Sabbath,” or, “a Sabbatism.” But the Sabbath thus reserved for God’s people, coincides with “the day of judgment and perdition of ungodly men.” Hence, a seven days’ uncleanness was typical of such a corruption of nature as is essential and, therefore, persistent to the end; and the exclusion of the defiled from the camp and the sanctuary signified the sentence of the judgment of the last day, when those whose natures are unrenewed, and whose sins are unpurged will be excluded from the Sabbath of redemption and from the new Jerusalem, and remain finally under the woe of the second death: “He that is filthy, let him be filthy still.... For without are dogs and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.”—Rev. xxii, 11, 15.
