Ye shall keep my Sabbaths. From these two passages it is manifest that the service of the tabernacle was annexed to the Sabbath, and that the two things were not only connected by an indissoluble tie, but that the rest from labor had reference to the sacrifices; since it would have been a mere mockery to rest without any ulterior object; nay more, after Moses has spoken of the rest, he seems to subjoin the reverencing of the sanctuary, as if it were the generic ordinance; so that the people might understand that all impediments were removed which are wont to withdraw them from the service of God. The expression, "fear the sanctuary," is a figurative one; but is equivalent to this, that they should shew by their very reverence of the sanctuary how truly and sincerely they fear God, who had promised that He would be present there, whenever He should be invoked. Exodus 34:21

Ye shall keep my sabbaths,.... The seventh day sabbaths, and the seventh year sabbaths; especially the former are meant, in which religious worship was given to the one true and living God, and therefore the observance of them is strictly enjoined; and hence this law follows closely upon the former, though Aben Ezra restrains it to the sabbatical years, or seventh year sabbaths, as he applies the sanctuary in the following clause to the jubilee year, which is said to be holy, Leviticus 26:12; supposing that this refers unto and stands in strict connection with the laws of the preceding chapter, concerning the sabbatical, Leviticus 25:1, and jubilee years, Leviticus 25:8,
and reverence my sanctuary; by attending in it, and on the worship in it, with reverence and godly fear, see Leviticus 19:30,
I am the Lord; who had a right to such religious worship, and to command such things, in which he ought to be obeyed, his sabbaths kept, and sanctuary reverenced.

Ye shall keep my sabbaths, and reverence my sanctuary--Very frequently, in this Book of the Law, the Sabbath and the sanctuary are mentioned as antidotes to idolatry.

My sanctuary - By purging and preserving it from all uncleanness, by approaching to it and managing all the services of it with reverence, and in such manner only as God hath appointed.
