The Third Commandment: You Shall Not Take the Name of the LORD Your God in Vain
Commandment Series by Heather Scarborough
“You shall not take the name of the LORD your God in vain, for the LORD will not leave him unpunished who takes His name in vain.”
Exodus 20:7
Israel had arrived at Mount Sinai. God had delivered them from Egypt, brought them through the Red Sea, sustained them in the wilderness, and established them as His covenant people. He had revealed Himself through His power, His promises, His provision, and His holiness. Now God was giving His Law, beginning with the most fundamental matters of their relationship with Him. The first commandment established who they were to worship. The second addressed how they were to worship Him. The third addressed the name of the God they worshiped.
“You shall not take the name of the LORD your God in vain.”
To understand the weight of this commandment, we need to understand what a name represented in biblical time. A name was more than a word used to identify someone. It could represent a person’s identity, character, reputation, authority, and work. A person’s name was connected to who that person was and what was known about him.
That is especially significant when the name belongs to God. God had made His name known to Israel through His actions and His dealings with them. His name was connected to the God who had delivered them from Egypt, spoken to them, entered into covenant with them, and revealed Himself as holy.
The Law itself revealed the character of the God who gave it:
“I am the LORD your God; consecrate yourselves and be holy, because I am holy.”
Leviticus 11:44
The commandments were not arbitrary rules. They revealed the holiness of the God who spoke them and established the standard by which His people were to live. That makes the third commandment much deeper than a prohibition against certain words.
The Hebrew wording helps us see why:
לֹא תִשָּׂא אֶת־שֵׁם־יְהוָה אֱלֹהֶיךָ לַשָּׁוְא
Lo tissa et-shem-YHWH elohekha lashav.
The phrase לֹא תִשָּׂא (lo tissa) carries the sense of “you shall not take,” with the verb נָשָׂא (nasa) meaning to lift, carry, or bear. שֵׁם (shem) means “name.” יְהוָה (YHWH) is the covenant name of the LORD, while אֱלֹהֶיךָ (elohekha) means “your God.” The final phrase, לַשָּׁוְא (lashav), comes from שָׁוְא (shav), carrying the ideas of emptiness, worthlessness, falsehood, or vanity.
Put together, the command carries the sense: “You shall not take, carry, or bear the name of the LORD your God in emptiness, falsehood, or worthlessness.”
The wording matters. God did not simply forbid Israel from speaking His name. He commanded them not to carry His name in vain.
One clear example was the use of God’s name in an oath. An oath made in the name of the LORD called upon God as the witness to what a person was saying. His name gave the words weight because the speaker was placing them under God’s authority. God’s name could not rightly be attached to a lie.
Leviticus states:
“Do not swear falsely by my name and so profane the name of your God. I am the LORD.”
Leviticus 19:12
The offense was more than telling a lie. God’s name had been attached to the falsehood.
The same principle applied to those who claimed to speak for God. A person could not put God’s name behind his own words and thereby give them divine authority. Jeremiah confronted prophets who claimed to speak for the LORD even though God had not sent them:
“Do not listen to what the prophets are saying to you; they fill you with false hopes. They speak visions from their own minds, not from the mouth of the LORD.”
Jeremiah 23:16
They were presenting their own words as though they came from God.
The third commandment concerns more than just profanity. It concerns truth and authority. We cannot make our opinion God’s truth simply by attaching His name to it. We cannot make our desires God’s will simply because we say, “God told me.” We cannot claim that God has spoken when He has not spoken, or use His authority to give our own words a weight they do not possess.
The seriousness of this commandment was reflected even in the way Israel eventually treated the pronunciation of God’s name. The nation became so concerned about violating the commandment that a practice developed of avoiding the pronunciation of the divine name. In writing, the vowels were removed, leaving the four consonants YHWH, known as the tetragrammaton. Yahweh is a common pronunciation today, although the exact ancient pronunciation is uncertain.
But avoiding the pronunciation of the name did not necessarily mean that a person was honoring it. A person could refuse to speak the name aloud and still misuse everything that the name represented. The issue was never merely the sound of the name. It was how the name was regarded and used.
Jesus addressed this same problem when He confronted the oath practices of the religious leaders. They had developed technical distinctions concerning what a person was actually bound by when making an oath—whether it was the temple or the gold of the temple, the altar or the gift on the altar. Jesus exposed the inconsistency:
“And he who swears by the temple swears by it and by the One who dwells in it.”
Matthew 23:21
Their technical distinctions could not remove God’s authority from what they were invoking. His name was not something to manipulate through careful wording.
Israel also needed to understand that the commandment was connected to their identity as God’s people. Before giving the commandments, God told them:
“Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, you will be for me a kingdom of priests and a holy nation.”
Exodus 19:5–6
They had been set apart. Their worship mattered. Their words mattered. Their promises mattered. Their conduct mattered. They belonged to the LORD, and what they did reflected upon the God they claimed to serve.
This is where the commandment reaches the heart. It is easy to hear “Do not take God’s name in vain” and think only of spoken words. But the commandment asks something deeper: What does my life say about the God whose name I claim?
If we claim God as our authority but disregard what He has commanded, what are we communicating about Him? If we speak about His holiness but treat sin casually, what are we saying about His character? If we tell someone, “God told me,” when God has not spoken, what have we done with His name? If we use God’s authority to justify our anger, preferences, opinions, or desires, have we honored Him or used Him for ourselves?
The heart can misuse God’s name even when the mouth never speaks it carelessly.
Proverbs 30 gives us a striking example:
“Two things I ask of you, LORD;
do not refuse me before I die:
Keep falsehood and lies far from me;
give me neither poverty nor riches,
but give me only my daily bread.
Otherwise, I may have too much and disown you
and say, ‘Who is the LORD?’
Or I may become poor and steal
and so dishonor the name of my God.”
Proverbs 30:7–9
The writer understood that dishonoring God’s name was not limited to words. His choices could contradict what he professed about God. Our words, promises, decisions, and actions can all either honor or dishonor the One whose name we claim.
God concluded the commandment with a warning:
“For the LORD will not leave him unpunished who takes His name in vain.”
Exodus 20:7
The person who carried God’s name in vain would be accountable to God Himself.
The third commandment calls us to recognize the weight of God’s name. To speak truthfully about Him, respect His authority, and refuse to use His name to advance our own purposes. It also asks us to examine whether our lives agree with the God we claim to serve.
Israel had been delivered from Egypt and brought to Sinai. The LORD had revealed Himself to them and made His name known. Now He commanded them not to carry that name into emptiness or falsehood.
His name represents who He is. And those who carry the name of the LORD must never carry it in vain.
