Sun (Heb. shemesh), first mentioned along with the moon as the two great luminaries of heaven (Genesis 1:14-18). by their motions and influence they were intended to mark and divide times and seasons. The worship of the sun was one of the oldest forms of false religion (Job 31:26, Job 1:31), and was common among the Egyptians and Chaldeans and other pagan nations. The Jews were warned against this form of idolatry (Deuteronomy 4:19; Deuteronomy 1:17; comp. 2 Kings 23:11; Jeremiah 19:13).
