The Lord bless thee. Blessing is an act of His genuine liberality, because the abundance of all good things is derived to us from His favor as their only source. It is next added, that He should "keep" the people, by which clause lie intimates that He is the sole defender of the Church, and protects it under His guardianship; but since the main advantage of God's grace consists in our sense of it, the words, "and make His face shine on you," are added; for nothing is more desirable for the consummation of our happiness, than that. we should behold the serene countenance of God; as it is said in Psalm 4:6, "There be many that say, Who will shew us any good? Lord, lift thou up the light of thy countenance upon us." Thus then I interpret this clause, that the people may perceive and taste the sweetness of God's goodness, which may cheer them like the brightness of the sun when it illumines the world in serene weather. But immediately afterwards the people are recalled to the First cause; viz., God's gratuitous mercy, which alone reconciles Him to us, when we should be otherwise by our own deserts hated and detested by Him. What follows, "The Lord lift up his countenance upon thee," is a common phrase of Scripture, meaning, May God remember His people; not that forgetfulness can occur in Him, but because we suppose that He has cast away His care of us, unless He actually gives proof of His anxiety for our welfare. Finally, it is added, may He "establish peace upon his people," which others translate a little less literally, [1] "put thee into peace:" and since this word signifies not only rest and a tranquil state, but also all prosperity and success, I willingly embrace this latter sense, although even its proper signification is not disagreeable to me.

Footnotes

1 - "Peace -- this word generally signifieth all prosperity, and the perfect enjoying of all good things; it is opposed to war, Ecclesiastes 3:8; to discord and emnity, Ephesians 2:14, 15; Luke 12:51; to tumult and confusion, 1-Corinthians 14:33; and to all adversity, Genesis 43:27; 2 Kings 4:26; Job 16:33 [sic]; and is therefore added for a conclusion of blessings, Psalm 29:11, and Psalm 125:4; 1-Peter 5:14. This peace is obtained by Jesus Christ, Ephesians 2:14, 15, 17; Romans 5:1; and enjoyed by the Holy Ghost, Romans 8:6, 9, and Romans 14:17." -- Ainsworth in loco.

2 - This latter sentence is much abbreviated in Fr.

The Lord bless thee, and keep thee - The second clause here, as in the other three verses, defines more closely the general tenor of the preceding one. The singular number, which is observed throughout, indicates that the blessing is conferred on Israel "collectively."

The Lord bless thee - There are three forms of blessing here, any or all of which the priests might use on any occasion. The following is a verbal translation: -
1. May Jehovah bless thee and preserve thee!
2. May Jehovah cause his faces to shine upon thee, and be gracious unto thee!
3. May Jehovah lift up his faces upon thee, and may be put prosperity unto thee!
This is a very comprehensive and excellent prayer, and may be paraphrased thus: -
1. May God speak good unto thee, by giving thee his excellent promises! (See the note on Genesis 2:3). May he preserve thee in the possession of all the good thou hast, and from all the evil with which thou art threatened!
2. May the Holy Trinity illuminate thy heart, giving thee the true knowledge of thyself and of thy Maker; and may he show thee his graciousness in pardoning thy sins, and supporting thy soul!
3. May God give thee communion with the Father, Son, and Spirit, with a constant sense of his approbation; and grant thee prosperity in thy soul, and in all thy secular affairs!
This I suppose to be the spirit and design of this form of benediction. Others will doubtless interpret it after their manner. Several wise and learned men believe that the mystery of the Holy Trinity is not obscurely hinted at in it. God the Father blesses and keeps his followers. God the Son is gracious unto sinners in remitting their offenses, which he died to blot out. God the Holy Spirit takes of the things which are Christ's, and shows them unto genuine Christians, and diffuses the peace of God in their hearts. In a word, Christ, the gift of the Father by the energy of the Holy Spirit, came to bless every one of us by turning us away from our iniquities.
1. Every genuine Christian is a true Nazarite. He is separated from the world, and dedicated solely to the service of God.
2. His life is a life of self-denial; he mortifies and keeps the flesh in obedience to the Spirit.
3. All this enters into the spirit of his baptismal vow; for in that he promises to renounce the devil and all his works, the pomps and vanities of this wicked world, and all the sinful lusts of the flesh - to keep God's holy word and commandments, and to walk in the same all the days of his life.
4. The person who is faithful has the blessing of God entailed upon him. Thus shall ye bless the children of Israel, etc., etc. See the notes on Numbers 6:5-7 (note).

The Lord bless thee,.... Jehovah, Father, Son, and Spirit; the word "Jehovah" being three times used, and a different accent put to each word, denoting three distinct persons and one Jehovah, according to Deuteronomy 6:4; who are each of them concerned in the blessing of the Lord's people, the spiritual Israel of God; Jehovah the Father blesses with all spiritual blessings, with electing, adopting, justifying, and pardoning grace, with regenerating and calling, and persevering grace, and with eternal life: Jehovah the Son blesses particularly with redeeming grace, and has a concern in all the other blessings; the saints are blessed with them in him, they are all in his hands, they are procured by him, come through him, and are the gifts of his grace: and Jehovah the Spirit blesses as a spirit of regeneration and sanctification, as the spirit of faith, as a comforter, as the spirit of adoption, and as the earnest and sealer of the saints unto the day of redemption:
and keep thee; from, the evil of the world, from the evil one Satan, from the evil of sin, and the power, prevalence, and dominion of it, and from falling totally and finally by it, and keep in a state of grace unto everlasting salvation.

Bless thee - Bestow upon you all manner of blessings, temporal and spiritual. Keep thee - That is, continue his blessings to thee, and preserve thee in and to the use of them; keep thee from sin and its bitter effects.
