blasphemed … with a curse: In biblical times, a name was more than a title. It represented a person's character, reputation, and origin. God is holy, and he required the Israelites to treat him as holy in all aspects of life (see Leviticus 10:3). God's instructed them to show respect for God's name (Exodus 20:7). Using God's name in a curse showed a sinful attitude toward God (Leviticus 24:15). It was punishable by death (24:13–16).
The Hebrew text in this passage uses two different words for "curse." One refers to a formal type of curse, while the other means a blasphemous or irreverent expression. These terms are used together in 24:15–16 to show the seriousness of the offense.
the Name: The Hebrew text referes only to "the Name." This wording shows care and respect for God's name.
