And the Lord spake unto Moses in mount Sinai. The purpose of the words, in Mount Sinai, is not to distinguish the place in which the sabbatical law and the law of the jubilee were given from that in which the preceding laws were delivered.
The words mean only, "in the Sinai district;'' and they are employed because these laws form the conclusion of the series of laws given while tile people were en-camped under Mount Sinai. The law on vows is, it is true, added to them, but it is by way of appendix.
