'Blasphemed' in the Bible

even though I was formerly a blasphemer [of our Lord] and a persecutor [of His church] and a shameful and outrageous and violent aggressor [toward believers]. Yet I was shown mercy because I acted out of ignorance in unbelief.

All who are under the yoke as bond-servants (slaves) are to regard their own masters as worthy of honor and respect so that the name of God and the teaching [about Him] will not be spoken against.
