Boyd’s Bible Dictionary:

(desert). [SINAI.]

Concise Bible Dictionary:

Shepherd with flocks before Mt. Horeb.
A mount closely connected with Sinai, and supposed to embrace the range of mountains lying about 28° 30' N, between the Gulf of Suez and the Gulf of Akaba, whereas Sinai is one of the mountain peaks. Horeb was called “the mountain of God” (Ex. 3:1). It was where God had intercourse with Moses, and where He made a covenant with Israel. Near here also the golden calf was set up (Ex. 17:6; Ex. 33:6; Deut. 1:2,6,19; Deut. 4:10,15; Deut. 29:1; Psa. 106:19). See SINAI.
