New International Version
10 Jesus called the crowd to him and said, “Listen and understand. 11 What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them.” 12 Then the disciples came to him and asked, “Do you know that the Pharisees were offended when they heard this?” 13 He replied, “Every plant that my heavenly Father has not planted will be pulled up by the roots. 14 Leave them; they are blind guides.[a] If the blind lead the blind, both will fall into a pit.” 15 Peter said, “Explain the parable to us.” 16 “Are you still so dull?” Jesus asked them. 17 “Don’t you see that whatever enters the mouth goes into the stomach and then out of the body? 18 But the things that come out of a person’s mouth come from the heart, and these defile them. 19 For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander. 20 These are what defile a person; but eating with unwashed hands does not defile them.”

“With the words, ‘You are not to take the name of God in vain,’ God at the same time gives us to understand that we are to use his name properly, for it has been revealed and given to us precisely for our use and benefit. Therefore, since we are forbidden here to use his holy name in support of falsehood and wickedness, it follows, conversely, that we are commanded to use it in the service of truth and of all that is good—for example, when we swear properly where it is necessary and required, or also when we teach properly, or, again, when we call on God‘s name in time of need, or thank and praise him in time of prosperity, etc. All of this is summarized in the command in Psalm 50:15, ‘Call on me in the day of trouble; I will deliver you, and you shall glorify me.’ All of this is what it means to call upon God‘s name to support the truth and to use it devoutly. In this way his name is hallowed, as we pray in the Lord‘s Prayer. (Martin Luther, The Large Catechism).
