si.nay is the named mountain and wilderness location where Israel camps, receives divine speech, and later departs.

The term consistently names Sinai as a location, especially the mountain where the LORD comes down, speaks with Moses, and gives commandments, and also the surrounding wilderness where Israel camps, is counted, and begins journeys.

1. Sinai as mountain of divine encounter and instruction · dominant

   The proper noun identifies the mountain in scenes of descent, speech, and commanded ascent: in Exodus 19:20 the APB renders the LORD as coming down on “Mount Sinai” and calling Moses upward, while Exodus 31:18 places the giving of the tablets there. Leviticus 26:46 likewise locates the giving of statutes and instruction on the mountain.

2. Sinai as the wilderness encampment and departure point · common

   The proper noun also occurs in clauses locating Israel in the wilderness: in Numbers 33:15 the APB renders their camping in the “wilderness of Sinai,” and Numbers 33:16 describes their setting out from it. Numbers 1:1 and Numbers 9:5 place speech and Passover observance in that wilderness setting.

In the Anselm Project Bible: The APB commonly presents the name as “Mount Sinai” when the clause concerns the mountain and as “the wilderness of Sinai” when Israel's camp or journey is in view. These phrases reflect the verses' location wording rather than separate lexical meanings.
