Rev. 13:5 – A mouth was given to him to speak boasts and blasphemies. He was also given authority to act for 42 months. 6He began to speak blasphemies against God: to blaspheme His name and His dwelling – those who dwell in heaven. (HCSB)
A mouth was given to him
The dragon, who has given the beast his power, authority and throne, also endows him with great rhetorical skills and he uses them to blaspheme God, His name, and His dwelling.
In the Old Testament, the root meaning of the word “blasphemy” is an act of effrontery in which a person insults the honor of God and for which he or she may be put to death by stoning (see Lev. 24:10-23; 1 Kings 21:9ff). In the New Testament, the meaning is extended to include God’s representatives. For example, Jews from the Freedman’s Synagogue accuse Stephen of “speaking blasphemous words against Moses and God” (Acts 6:11).
