Exodus 40:10

An altar most holy. Not really more holy than the rest of the tabernacle and its contents, which are all pronounced" most holy" in Exo_30:29; but requiring more to have its holiness continually borne in mind, since "it was more exposed to contact with the people" than the tabernacle and its vessels (Keil).

HOMILIES BY D. YOUNG Ver. 10. The altar most holy.

There is a difference at once perceptible between the words of sanctifying in ver. 9, and the words of sanctifying in ver. 10. Whereas the tabernacle and all therein are declared as holy, a special sanctity is somehow attached to the altar of burnt offering. "It shall be an altar most holy." The reasonable explanation of this is, not that there was any special sanctity in the altar of burnt offering itself, but that from its exterior position it was in great danger of being treated thoughtlessly, and therefore needed special attention to be called to it. Hence we are led to note the existence of a similar distinction among such things as we are bound to treat in a reverent and careful manner. Certain persons, things, and places are of such a kind as to be their own protection. Perhaps it is still true to some extent, though doubtless it was much more felt in former times, that there is a divinity which doth hedge a king. Men of coarse and scandalous tongues manage to put a check on them selves in the presence of women and children. Some are still alive who remember the horror and indignation excited by the resurrection-men of fifty or sixty years ago, and how little watch-houses were built in some churchyards, and men took it in turns to guard by night the resting-places of their beloved dead. But those who would shrink with loathing from the bare possibility that they could be guilty of such desecration are nevertheless found treating great realities of holiness with indifference, if not with contempt. Remember with what profaning hands the Holy One of God was abused; he who spake concerning the temple of his body; he who was holy, not by any mere association, not for the purposes of some temporary economy, but essentially holy. Are there not those who, thoughtless enough of all the evil they are doing, crucify the Son of God afresh, and put him to an open shame? (Heb_6:6) What a fearful outlook is indicated for those who tread underfoot the Son of God, and count the blood of the covenant, wherewith they are sanctified, an unholy thing, and do despite unto the spirit of grace! (Heb_10:29) The very same thing may in one way be hallowed, and in another be desecrated. There is a great semblance of hallowing in the huge family Bibles so often seen in English houses, rich, and not unfrequently tawdry, in their binding and gilding; but after all they may only be there as part of a reputation for respectability. The true hallowing is in the dog"s-eared, well-worn book, poorly printed it may be, and on common paper, and with that indefinable appearance about it which tells of constant use. It is only too easy a thing to put superstition in the place of an intelligent, diligent, profound, and practical reverence. Even Christians are strangely negligent concerning the holiness inherent in them if they are really born again. Very unobservant are they of the persistent references in the New Testament to the holiness of a Christian"s personality. How much is done, as a matter of course, that is inconsistent, yea, scarcely compatible with being, indeed, a living sacrifice! Y.

AND THE ALTAR SHALL BE MOST HOLY. Since they would also sacrifice on it the most holy offerings, Scripture describes the altar as “most holy,” even though it stood in the court of the Tabernacle. Of the Tabernacle, however, Scripture says, and it shall be holy, because the term “most holy” is used usually only with reference to the place where the ark rests, just as it is said, and the veil shall divide unto you between the holy place and the most holy. It is possible that He said of the altar “most holy,” because it sanctifies other things, just as He said, whatsoever toucheth the altar shall be holy., 29:37. See also Ramban above in Seder Ki Thisa 34:25, towards the end, for the specific explanation of how the altar sanctifies whatever touches it.
