In biblical theology, the name (šēm) of the Lord is central to the covenant he made with Israel. The Lord revealed himself to Moses by speaking his name (Exodus 3:14). According to Ross A name represents the whole person and thus becomes a powerful force, as powerful as the person named. A name could be blotted out, redeemed, praised, prayed to, preserved for an inheritance, made famous, win battles, or dwell among individuals.
1 Therefore, the improper use of the Lord’s name was an outward expression of contempt for the person of God.
11 and the Israelite woman’s son blasphemed the Name, and cursed. Then they brought him to Moses. His mother’s name was Shelomith, the daughter of Dibri, of the tribe of Dan.
