The third commandment (Exodus 20:7) is usually reduced to a ban on profanity or careless oaths such as "OMG," but it reaches much deeper for those in covenant with God. It forbids any words or behavior that reflect negatively on Him, and it bridges the commands against idolatry and those against unrighteous conduct. Its meaning hinges on three Hebrew words. The verb nā&347;ā' means to lift, carry, or bear, as in Cain's "greater than I can bear" (Genesis 4:13), so God is concerned with how His people carry His name in all their daily activities, not just in outbursts of temper. The noun shem means name, but when applied to God it reveals His character and actions, as shown in His proclamation to Moses in Exodus 34. Bearing His name therefore concerns the quality of godly example before others, which makes the commandment about righteous witness. The word translated "vain," shāw', means deceit, falsehood, emptiness, and worthlessness rather than conceit. God thus forbids His people to deceive others about Him or to devalue Him and His righteous character. Positively, they are to express the truth about God and His way in every thought, word, and deed (I Corinthians 10:31; Colossians 3:17), bearing His name worthily. Profanity is included, but the commandment binds Christians to a standard in which every activity brings glory and honor to God.

The third commandment concerns far more than profane or false speech. The Hebrew verb nasha means to lift, carry, or bear, so the commandment forbids bearing God's name in vain, which covers all behavior and not only the voice. God's name stands for His being, His character, and His possession of us as His children. As signatories of the New Covenant, we carry His name wherever we go, in our speech, demeanor, attitudes, decisions, advice, dress, and grooming. Anyone with a little knowledge of God should be able to look at us and see the family resemblance. The word shav (in vain) means emptiness, falsehood, or anything insubstantial and worthless, like a vapor or the film of a soap bubble. To bear the name in vain is to do so thoughtlessly, in a careless, rote, or mechanical way, or unrighteously, in a false, unworthy, and sinful way. This commandment therefore governs the quality of our worship and our whole lives. We represent a perfectly righteous and holy God, so we must never sully His precious name by speech, behavior, or attitude. It is sin, and God will not hold guiltless the one who does it. Our lives are meant to give His name the highest honor and glory.

The third commandment states that one shall not take the name of the LORD one's God in vain, for the LORD will not hold guiltless anyone who does so. This instruction carries a dual sense. It prohibits swearing falsely by the name and also bars profaning the name through speech or conduct that brings dishonor upon God. The commandment extends to one's behavior as a bearer of the name, so that calling oneself a follower of God while acting in ways that discredit Him constitutes a violation. It addresses profanity and euphemisms as well, yet it says nothing about which specific name must be used or how it must be pronounced. Certain interpreters take the commandment to an extreme by insisting that God can be addressed only by the Hebrew name YHWH, or Yah, and that Jesus can be addressed only by Yeshua. They reject English terms such as God or Lord, along with Greek equivalents such as Theos or Kurios, on the ground that these derive from pagan sources. They maintain that God will respond to no other names. This position, however, adds a requirement absent from the commandment itself. Scripture records many names and titles for God, each revealing an aspect of His character, and the New Testament employs Greek terms without condemnation. The emphasis falls on the meaning conveyed by the name rather than on its linguistic form or exact pronunciation. By elevating one narrow understanding of the name into the central requirement for acceptable worship, adherents effectively create an idol. They concentrate on correct pronunciation while allowing other aspects of obedience to fall away, much as the Jews of Jeremiah's day trusted in the physical Temple while neglecting amendment of life. Such an approach mirrors the self-righteous Pharisaism that the commandment was meant to prevent. It substitutes human tradition for the plain intent of the command and turns a means of honoring God into an object of misplaced devotion. The broader message of the material warns that adding to or taking from God's instructions in this manner constitutes a form of idolatry that exalts personal interpretation above faithful obedience.
