Aaron’s Benediction numbers 6:22-27 (nasb)
Then the LORD spoke to Moses, saying, “Speak to Aaron and to his sons, saying, ‘Thus you shall bless the sons of Israel. You shall say to them:
The LORD bless you, and keep you;
The LORD make His face shine on you, And be gracious to you;
The LORD lift up His countenance on you, And give you peace.’
“So they shall invoke My name on the sons of Israel, and I then will bless them.”
No shawl, no hand gesture, no Jewish tradition, will make this more efficacious. It was between God, Moses, Aaron and his sons, and Israel. When Hebrew Roots movement person says this to me, while wearing a shawl, and doing the traditional hand gesture that goes along with it, I wonder to myself, “Why? Why are they doing this? Why are they doing it the way they are doing it?” Before you say, “I’ve never seen anyone do that!” Think about it, you might not have, but that doesn’t mean it isn’t happening. Just do a quick google or youtube search for, “Aaronic blessing Numbers 6” and you’ll see the lunatic fringe. This is what happens when people trade legalistic traditions for the gospel. There is only one who saves. It is Christ Jesus. You can call yourself a Christian, or Hebrew Roots, or whatever, but if your faith is so bound up in Jewish traditions instead of the Christ who is the perfection of all sacrifice and work, you are missing the boat.
Here is what the Matthew Henry Concise Commentary has to say,
The priests were solemnly to bless the people in the name of the Lord. To be under the almighty protection of God our Saviour; to enjoy his favour as the smile of a loving Father, or as the cheering beams of the sun; while he mercifully forgives our sins, supplies our wants, consoles the heart, and prepares us by his grace for eternal glory; these things form the substance of this blessing, and the sum total of all blessings. In so rich a list of mercies worldly joys are not worthy to be mentioned. Here is a form of prayer. The name Jehovah is three times repeated. The Jews think there is some mystery; and we know what it is, the New Testament having explained it. There we are directed to expect the blessing from the grace of our Lord Jesus Christ, the love of the Father, and the communion of the Holy Ghost, 2Co_13:14; each of which Persons is Jehovah, and yet they are not three Lords, but one Lord.
