Buttmann, 21f (19)), indeclinable, Josephus, τό Σιναιον, Antiquities 3, 5, 1, and τό Σιναιον ὄρος, Antiquities 2, 12, 1; Hebrew ñÄéðÇé (perhaps ’jagged’; others make it an adjective ’belonging to (the desert of) Sin’) (Sina or) Sinai, a mountain or, rather, a mountainous region in the peninsula of Arabia Petraea, made famous by the giving of the Mosaic law. There are three summits: one toward the west, which is called çåäÅá, a second toward the east, Sinai proper so called, the third toward the south, now Mount St. Catharine. But the distinction between Horeb and Sinai is given differently by different writers; and some think that they were two different names of one and the same mountain (cf. Sir 48:7); cf. (McClintock and Strong’s Cyclopaedia, under the word ); Winers RWB, under the word Sinai; Arnold in Herzog edition 1 vol. xiv., p. 420f; (Schultz in edition 2 vol. xiv., p. 282ff); Furrer in Schenkel v., p. 326ff; (English Ordnance Survey, 1869; Palmer, Desert of the Exodus, 1872; also his Sinai from the Monuments, 1878; Furrer commends Holland’s Sketch Map etc. in the Journ. of the Royal Geog. Soc. vol. 39 (Lond. 1869)). The name occurs in Act 7:30; Act 7:38; Gal 4:24 f.
