The Torah says:
וַיְדַבֵּ֨ר יְהוָ֧ה אֶל־מֹשֶׁ֛ה בְּמִדְבַּ֥ר סִינַ֖י בְּאֹ֣הֶל מוֹעֵ֑ד -- The Lord spoke to Moses in the wilderness of Sinai, in the Tent of Meeting. [Numbers 1:1]
Ibn Ezra and others explain that the reason for specifying the location is to inform us that Moses did not have to go up to Mount Sinai to hear from God, as he did before, since God was now present in the Tent of Meeting.
But then, why not say just “in the Tent of Meeting” and omit “in the wilderness of Sinai”?
(There are other reasons in the Sources for mentioning the wilderness, but I want to focus on this one because it seems incomplete to me.)
