The Aaronic blessing (Numbers 6:24-26) meaning

Short answer

The Aaronic blessing is the priestly blessing God gave Aaron and his sons to speak over Israel. It asks the Lord to bless and keep His people, to show them His favor and grace, and to give them peace, and God promised to stand behind it Himself. Christians still use it as a benediction and often see in its three lines a hint of the Father, the Son and the Holy Spirit.

The Aaronic blessing, also called the priestly blessing, is one of the oldest and best-loved prayers in the Bible. Many churches close their services with it, parents speak it over their children, and it is often chosen for baptisms and weddings. Here is where it comes from and what each of its lines means.

God’s own words for blessing His people

And the LORD spoke unto Moses, saying, Speak unto Aaron and unto his sons, saying, On this wise ye shall bless the children of Israel, saying unto them,
Num 6:22–23 · King James Version (1769)

The blessing stands at the end of the first part of Numbers. John MacArthur notes that the opening chapters, which order Israel’s camp and its purity, close with a request for God’s blessing on His people, just as the next section closes with one (Numbers 10:35–36). An obedient people, set apart for the Lord, receives His favor.

Matthew Henry points out something unusual. For other parts of worship God gave no fixed form, but here He put the exact words into the priests’ mouths, so that no one could think the blessing was their own invention. Still, John Wesley notes that the priests were not tied to these words alone: Moses, David and Solomon later blessed the people in other words. The Dallas Theological Seminary commentators compare it to the Lord’s Prayer: a pattern as much as a formula.

According to Jewish tradition, recorded by Barnes and the Lopukhin Bible, the priests spoke this blessing at the close of the daily sacrifice, and it is still used in synagogue worship.

Three lines, rising to peace

The LORD bless thee, and keep thee: The LORD make his face shine upon thee, and be gracious unto thee: The LORD lift up his countenance upon thee, and give thee peace.
Num 6:24–26 · King James Version (1769)

Albert Barnes observes that the blessing is rhythmic and has three parts, each rising above the one before, until it reaches peace, the fullest gift God can give His people. In each line the second half explains the first.

Bless and keep. God’s blessing is His goodness in action. To keep means to guard: Keil and Delitzsch, citing Calvin, describe God as the only defender of His people. MacArthur sums up the results of the blessing as God’s protection, His grace and complete well-being.

His face shining. Wesley compares this to the sun shining on the earth to give it light and warmth and to renew it. He paraphrases it this way: the Lord love you and let you know that He loves you. Barnes adds that God’s face means His active, personal attention, and to that light the line adds grace, His mercy to people who do not deserve it.

His face lifted up, and peace. To lift up one’s face toward someone is to look at him with care. Barnes explains it as God turning His thoughts toward His people. The last word is peace, shalom. Keil and Delitzsch call it the sum of all the good God gives His people, and Wesley lists peace with God, with one’s own conscience and with others.

The word “thee” is singular. Barnes reads it as Israel addressed as one people, while Henry stresses that the blessing reaches each person: everyone who receives God’s word may receive the blessing as if their own name were written in it.

God’s name on His people

And they shall put my name upon the children of Israel; and I will bless them.

Num 6:27 · King James Version (1769)

In the Bible a name stands for the person. MacArthur explains that God’s name expressed His character, and the priests were calling on God to live among His people and meet all their needs. The New Geneva Study Bible says the blessing expresses God’s wish to clothe His people with His name, which is the same as giving them Himself.

The power of the blessing is not in the priest. Barnes notes that God Himself gives effect to the words His servants speak, and Henry records the Jewish teachers’ warning not to look down on a blessing because the priest is an ordinary man: its effect depends on the holy God, not on him.

The Trinity and the blessing of Christ

The name of the Lord is repeated three times. Henry writes that the Jews sensed a mystery here and the New Testament explains it, pointing to Paul’s closing blessing:

The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all. Amen.

2 Cor 13:14 · King James Version (1769)

William MacDonald calls this one of the most wonderful blessings in the New Testament and the only one that names all three Persons of the Trinity. Barnes, Henry and Jamieson, Fausset and Brown see the work of the Father, the Son and the Spirit shadowed in the three lines of the Aaronic blessing. Keil and Delitzsch are more careful: they see truth in this reading but think the threefold repeat mainly expresses the fullness of God’s blessing. Either way, Christians receive this blessing from the one God who has made Himself known as Father, Son and Holy Spirit.

Henry also sees in the priestly blessing a picture of Christ, who was sent to bless us (Acts 3:26). The last thing Jesus did on earth was to lift up His hands and bless His disciples (Luke 24:50–51).

So when a pastor ends a service with these words, or parents pray them over a child, it is not a magic formula. It is a prayer God Himself gave, and He has promised to answer it.
