Numbers 6:22–27 is God's own prescription for the Aaronic Benediction. The formula is given to Moses for Aaron and his sons: this is how you shall bless the people. The Lord bless you and keep you; the Lord make His face shine on you and be gracious to you; the Lord turn His face toward you and give you peace. Three clauses, each one invoking the divine Name over the congregation. The final verse adds God's own interpretation: so shall they put my name on the people of Israel, and I will bless them. The Benediction is not a wish expressed by the pastor; it is the placement of the Name upon the people, authorized by God Himself, carrying the blessing He has attached to that Name.
Psalm 115:14's "May the Lord give you increase, you and your children" is itself a benediction in the pattern of Numbers 6, a blessing over households in the mode of prayer. The household's greatest need, the psalm implies, is not material provision managed through human effort but the increase that comes from the Lord's Name resting upon it. Luther's treatment of the Second Commandment in the Large Catechism begins by insisting that the Name was given not merely to be protected from misuse but to be used rightly in exactly this way: placed upon the people, invoked in every need, spoken in blessing, prayer, praise, and thanksgiving across every day of the household's life.
Numbers 6:27 says the purpose of the Benediction is to put God's name on the people. Psalm 115:14's prayer for increase over households reflects the same theology. Luther's Second Commandment treats the Name as given for positive use. How does understanding the Benediction as the placement of the Name upon the people, rather than as a pleasant closing formula, change the way the congregation receives it at the end of the Divine Service?
| Term |
What It Means |
| The positive use of the Name |
Luther's central claim about the Second Commandment: God gave His Name not merely to restrict its misuse but so that it may be of constant use and profit. The commandment requires the Name to be called upon in every time of need, and worshiped with prayer, praise, and thanksgiving. |
| A real, actual, living blessing |
Luther's distinction between a human wish and the divine Benediction. A human blessing is a mere word; when God's name is invoked over the congregation, it creates what it says. The Aaronic Benediction actually delivers the grace, peace, and preservation it proclaims. |
| The Name as weapon against the devil |
Luther's pastoral use of the Second Commandment in the household: the devil is loath to hear God's name and cannot remain long where it is uttered from the heart. Morning prayer, meal blessing, and invoking the Name in sudden moments of fear are all acts of spiritual warfare. |
| The greatest abuse: false preaching |
Luther's identification of the worst violation of the Second Commandment: not perjury or cursing, but false preachers who offer their lies and human inventions as if they were God's Word, decking themselves out with God's name as a cloak for shame. |
Luther says the devil is loath to hear God's name and cannot remain long where it is uttered from the heart, and encourages households to keep the Name constantly on their lips through prayer, blessing, and invocation in sudden moments of fear. Psalm 115:14's prayer for household increase presupposes that the Lord's name is already being invoked there. What specific practices does Luther prescribe for the household, and what would it take for your congregation's families to recover them?
From the First Commandment to the Second
Luther's Large Catechism reads the Decalogue as a logical progression, and his treatment of the Second Commandment begins by naming its relationship to the First. The First Commandment instructs the heart, establishing the foundation of trust in God above all things. The Second Commandment directs the mouth and tongue, since words are the first things that spring from the heart. The person whose heart trusts in God will use God's Name rightly, because the Name is the instrument through which the First Commandment's trust is expressed outwardly. The Second Commandment is the First Commandment's voice. The commandment's positive content is central to Luther's reading. God gave His Name not merely to restrict its misuse but for the very purpose that it may be of constant use and profit. This means the commandment requires something, not only prohibits. It requires the Name to be called upon in every time of need, and requires worship through prayer, praise, and thanksgiving. Numbers 6's Benediction is the commandment's positive form in its most majestic expression: the Name placed upon the people by ordained authority, delivering the blessing God attached to it. Psalm 115:14's prayer for increase is the household's daily practice of the same positive requirement: the Name invoked over the people who depend on it for everything they need.
Luther says the Second Commandment's primary content is positive: the Name is given for constant use and profit, to be called upon in every time of need and worshiped with prayer, praise, and thanksgiving. How does a congregation that understands this teach its members to use the Name rightly across the week, not only in the Divine Service but in the household's daily life of prayer and blessing?

A Real, Actual, Living Blessing
Luther's most striking claim about the Benediction is its distinction from human wishing. He draws the contrast explicitly: a human blessing is often a mere word, nothing more than a good wish with no power to create what it wishes. But when God's Name is invoked over the congregation in the Benediction, it is a real, actual, living blessing that creates what it says or blesses. The Aaronic Benediction does not express the pastor's hope that the congregation might be blessed; it places the Name of the God who keeps, illumines, and gives peace upon the people, and the God who authorized that placement attaches His blessing to it. Numbers 6:27 is the authority for this claim: I will bless them. The placement of the Name and the bestowal of the blessing are God's own act; the ordained minister is the authorized instrument through whom the Name is placed, but the blessing is entirely God's doing. Psalm 115:14's prayer for increase is the household's acknowledgment that the same logic applies to every invocation of the Name: the increase that comes to a family is not the product of their own labor alone but of the Name that rests upon the household because God has attached His blessing to its being spoken there. Luther urges families to keep the Name in constant use precisely because it is this kind of word: one that does not return empty.
Luther says the Benediction is not a wish but a real, actual, living blessing that creates what it says, with God Himself as its author. Numbers 6:27 grounds this in God's own promise: I will bless them. How should this claim change what happens in the congregation both when the pastor pronounces the Benediction and when a parent prays over a child at bedtime or a family invokes the Name at a meal?

The Name in the Household and Against the Devil
Luther's pastoral application of the Second Commandment extends the Benediction's logic into the daily life of every household. The Name is to be kept constantly on the lips not merely as a liturgical act but as a habit that drives out the devil. Luther writes that the devil is very loath to hear God's name and cannot remain long where it is uttered and called upon from the heart. This is not a superstition; it is a theological consequence of the Name's power. The same Name that creates blessing when spoken in the Benediction creates protection when invoked in the morning prayer, the meal blessing, the sudden cry for help in a moment of fear. Luther's specific prescriptions for the household are practical and daily: morning and evening prayers, giving thanks at meals, teaching children to cry out Lord God, protect us or Help, dear Lord Jesus in moments of terror. The household that keeps the Name in constant use is the household Psalm 115:14 envisions: one whose increase and whose children's increase both depend on the Lord's name resting upon them. The Second Commandment's prohibition of misuse is the boundary that protects the Name's power; the positive command is the invitation to use it constantly and confidently, so that what the Benediction places upon the congregation on Sunday is carried home and spoken through the week.
Luther prescribes specific daily household practices: morning and evening prayer, meal blessing, and teaching children to invoke the Name in sudden moments of fear. These are not pious additions to Christian life; they are the Second Commandment's positive requirement lived out in the household. What specific practices from Luther's prescription are most absent in the households of your congregation, and what would it take pastorally to recover them as a matter of obeying the commandment rather than merely adopting a devotional habit?
The Payoff
The Aaronic Benediction's three clauses, the Lord bless you and keep you, the Lord make His face shine on you, the Lord turn His face toward you and give you peace, are the Name placed upon the people in its fullest form. Psalm 115:14's prayer that the Lord give increase to you and your children is the same Name invoked over the household in its daily need. The Second Commandment's positive command is the instruction to keep this Name in constant use, from the Sunday Benediction through the week's prayers and blessings and invocations, so that the household that hears the Name placed upon it in the assembly carries it home as a living word that blesses, protects, and creates what it promises.
