20:7 takes his name in vain. God’s name was a gift of grace to Israel. Not through an idol, but in the name, Israel had access to God in worship. God’s name is therefore to be revered. This command forbids the use of God’s name in false worship, for incantations or divination, as well as for attesting falsehood or speaking blasphemy (Deut. 28:58). Jesus taught His disciples to pray that God would hallow His name, and Jesus hallowed the Father’s name on the Cross (Matt. 6:9; John 12:27, 28).
